Question 6 • WI-Mathematics Grade 8 A

A line has a slope of –3/2 and has a y-intercept of 3. What is the x-intercept of the line?

Answer
A
–3
B
–2
C
2
D
3

Explanation

A line with slope −3/2 and y-intercept 3 has equation y = (−3/2)x + 3. At the x-intercept, y = 0, so 0 = (−3/2)x + 3, which gives x = 2. Therefore, the x-intercept is 2, choice C.
