What is the x-intercept of the line with the equation y = 3x − 6?
A) −6
B) - 1/2
C) 0
D) 2
E) 3
KEY CONCEPT: The x-intercept is the point where the y-coordinate = 0So, take the equation of the line, y = 3x - 6, and replace y with
0 to get:
0 = 3x - 6
Solve, to get x = 2
So, the point (2, 0) lies ON the line, which means the x-intercept is 2
Answer: D
Cheers,
