Xintercept is something of the form (x, 0)
So if y=0 then -4x-3=0; -4x=3; x= -3/4

The x-intercept is the x-coordinate of the point where the line intersects the x-axis. At the x-axis, every point has 0 for its y-coordinate.
Let y = 0, and solve for x.
y = -4x - 3
-4x - 3 = 0
-4x = 3
x = -3/4
The x-intercept is -3/4.
