find the x- intercept of the line by substituting 0in for solving for x

To find the x-intercept of a line, you need to set y equal to 0 in the equation of the line and solve for x. Here are the steps:

1. Write down the equation of the line. It should be in the form y = mx + b, where m is the slope and b is the y-intercept.

2. Substitute 0 for y in the equation. This gives you 0 = mx + b.

3. Solve the equation for x. This involves subtracting b from both sides of the equation to get -b = mx, and then dividing both sides by m to get x = -b/m.

The x-intercept of the line is the value of x you found in step 3.
