What is the x-intercept of y = 4x – 4?

1
0
4
-4

The correct answer is: 0

An x-intercept is the point where the graph of a line crosses the x-axis, meaning the y-coordinate is equal to 0. In this equation, y is equal to 0 when x is equal to 1, making the x-intercept (1,0). The other options, A, C, and D, do not represent the x-coordinate of the x-intercept. Option A, 1, is the y-intercept instead. Option C, 4, is the slope of the line. Option D, -4, is the y-intercept if the equation was written in slope-intercept form. Therefore, the x-intercept of this equation is 0.
