When you find the given solution of the equation for the intercept method, you get confused in doing complex calculations manually. To get rid of this situation, you need an x and y intercept finder that provides you with a correct solution for the intercept problem from the given equation.

What is an Intercept?

An intercept is a method to find the intercept point where coordinate axes are met on a graph in linear algebra. There are two types of intercepts which are the x-intercept and the y-intercept for the slope of the equation

The x-intercept is found when you take the value of y which is equal to zero in the given equation. Similarly, the y-intercept is found when you put the value of x as equal to zero.

These intercepts provide you insights and the behavior of the given function. The x & y intercept calculator expresses the x-intercept in the following form:

Set y to 0:

$$ 0 \;=\; mx + b $$

Solve for x:

$$ mx \;=\; -b $$

$$ x \;=\; -\frac{b}{m} $$

The y-intercept can be expressed as,

Set x to 0:

$$ y \;=\; m(0) + b $$

Solve for y,

$$ y \;=\; b $$

How to Calculate Intercepts?

When calculating the intercepts of an equation, the x intercept and y intercept calculator finds two points where the graph of the equation crosses the x-axis and y-axis.

Let's understand how to find x and y intercepts in steps. These steps are used to calculate x and y intercepts accurately.

To y-intercept

To know how to calculate the y-intercept for the given equation, follow the given steps which are:

Step 1:

First, you need to identify whether the given equation is written in the standard form of the slope-intercept form as y=mx+b or not. If it is not then rewrite the given equation in standard form (in linear).

Step 2:

Put x=0 in the slope of equation y=mx+b, to find the intersection point where they met from the equation.

Step 3:

Solve the equation to find the y-value points for the slope of the equation.

Step 4:

After finding the value of the y axes, the y-intercept from the given equation, you get the points that pass through a line during the intersection on the y-axis as (0,y).

To x-intercept

To find the x-intercepts for the equation some steps should be followed. Let’s understand how the x and y intercepts calculator solves the equation accurately.

Step 1:

First, start with the equation of slope y=mx+b, and see if the given equation is written in the slope of the equation pattern or not.

Step 2:

Put y=0, to find the value of x, because of the x-intercept, the graph crosses the x-axis.

Step 3:

After that solve the equation for the x value for the slope on the graph.

Step 4:

Lastly, you get the point (x,0) at the x-axis from the given equation of the slope.

Solved Example of Intercept

The x y intercept calculator will help you calculate x and y intercepts but its necessary for you to understand how to find x and y intercepts manually so an example is given below,

Example: Find x and y intercepts

$$ y \;=\; -3x + 9 $$

Solution:

For x intercept y=0

$$ y \;=\; -3x + 9\; \; \; Set \;y \;=\; 0 $$

$$ 0 \;=\; -3x + 9 \; \; Solve\; for\; x $$

$$ 3x \;=\; 9 $$

$$ x \;=\; 3 $$

After solving the equation we get two points (0,3)

For y intercept x=0

$$ y \;=\; -3x + 9 \; \; Set\; x \;=\; 0 $$

$$ y \;=\; -3(0) + 9\; \; Solve\; for\; y $$

$$ y \;=\; 9 $$

The y-intercept point is (0,9)

FAQs

How do you find the x and y intercepts quickly? ›

To find y-intercept: set x = 0 and solve for y. The point will be (0, y). To find x-intercept: set y = 0 and solve for x. The point will be (x, 0).

How do you find the x and y intercepts of a function? ›

Intercepts are those points on a Cartesian coordinate system where the graph of an equation or function crosses the x- and y-axes. To find the x-intercept algebraically, simply set y to 0 and solve for x. Conversely, to find the y-intercept, set the value of x to 0 and solve for y.

What is the y-intercept of the line calculator? ›

To find the y-intercept of a line given by ax + by + c = 0, follow these simple steps: Substitute the value x = 0 into the line equation to get by + c = 0. Rearrange this equation to find the y-intercept yc, as yc = −c/b.

What is the fastest way to find the y-intercept? ›

Since the y-intercept always has a corresponding x-value of 0, replace x with 0 in the equation and solve for y. On a graph, the y-intercept can be found by finding the value of y when x=0. This is the point at which the graph crosses through the y-axis.

Which equation is the easiest to identify the x intercepts? ›

The equation that is the easiest to identify the x-intercepts is the factored Form. Option A is the correct answer. We have, In factored form, the equation is written as a product of linear factors, and the x-intercepts (or roots) are easily identifiable by setting each factor equal to zero and solving for x.

How to find y-intercept with 2 points? ›

Use the slope and one of the points to solve for the y-intercept (b). One of your points can replace the x and y, and the slope you just calculated replaces the m of your equation y = mx + b. Then b is the only variable left. Use the tools you know for solving for a variable to solve for b.
