Question

Which of these are the intercepts of the graph of y = 3x – 12?

(4, 0), (0, -12)
(12, 0), (0, 4)
(3, 0), (0, 4)
(4, 0), (0, 3)
(-4, 0), (0, -12)

Answer 1

The answer is (4, 0), (0, -12)

y = 3x - 12

x-intercept:
y = 0
0 = 3x - 12
12 = 3x
x = 12/3
x = 4
Intercept: (4, 0)


y-intercept
x = 0
y = 3 * 0 - 12
y = 0 - 12
y = -12
Intercept: (0, -12)
