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