# x-Intercept Calculator

The x-intercept is defined as the point where the line crosses the x-axis. The general form of the x-intercept of the equation of the line is (-c / a,0)

## How to Find x-Intercept?

The x-intercept of a graph is (are) the point(s) where the graph intersects the x-axis. So the y-coordinate of any point on the x-axis is 0.

The equation of straight line in general form ax + by + c = 0

For y-intercept, y = 0, ax + b(0) + c = 0

⇒ ax + c = 0

⇒ ax = -c

⇒ x = -c / a

Thus, the x-intercept of the equation of a line in general form is:

**x-intercept is (-c / a,0)**

**Solved Example:**

Find the x-intercept for given equation 3x + 5y + 6 = 0?

**Solution:**

Given equation: 3x + 5y + 6 = 0

y-intercept is ( -c / a,0)

= ( -6 / 3, 0) = (-2, 0)

or substitute y = 0, 3x + 5(0) + 6 = 0

⇒ 3x + 0 + 6 = 0

⇒ 3x = -6

⇒ x = -6 / 3

⇒ x = -2

Therefore, y-intercept is (-2, 0)

Similarly, you can use the calculator to find the value of x-intercept for the following:

- 5x - 4y - 4 = 0
- 7x + 6y - 8 = 0
