Question

What are the x and y intercepts of the graph of 3x + 4y = -36?

a) x-intercept = -9, y-intercept = 12
b) x-intercept = -12, y-intercept = -9
c) x-intercept = 12, y-intercept = -9
d) x-intercept = 9, y-intercept = -12

Answer 1

d

Explanation:

Answer 2

3x+4y=-36

First we need to put this in slope-intercept form. Start off by subtracting 3x from both sides.

4y= -3x+36

Now divide both sides by 4

y= -3/4x+9


Now, graph the equation and go from there. Your answer will be x=12 and y=9
