Question

What is the x−intercept and y−intercept of the graph of 3x − 4y = 12?

x−intercept = (−4, 0); y−intercept = (0, 3)

x−intercept = (4, 0); y−intercept = (0, −3)

x−intercept = (0, −3); y−intercept = (4, 0)

x−intercept = (0, 3); y−intercept = (−4, 0)

Answer 1

Hint:

To find the x-intercept, plug in y = 0 and solve for x

To find the y-intercept, plug in x = 0 and solve for y

Answer 2

I'll do the x-intercept to get you started

3x − 4y = 12

3x − 4(0) = 12 ... plug in y = 0

3x - 0 = 12

3x = 12

x = 12/3

x = 4

So the x-intercept is (4,0)
