- To find the x- intercept, always set y as 0.
- Similarly, to find the y - intercept, set x equivalent to 0.
- Further simplify the equation to get either of the intercepts.

Here is an example to solve a problem on identifying x- and y- intercepts. Let’s look at the given example mentioned below to understand more about the concept.

Q: Find the y-intercept of the line: y − 9 = 3x

Step 1: To determine y, set x for 0.

So,

Y - 9 = 3 * 0.

Step 2: Simplify the equation.

Y - 9 = 3 * 0

Y - 9 = 0

Y = 9.
