Answer is you need to multiply 8 2/3 x 5 3/4 = 49 5/6
15% = 0.15
0.15 x 20 = 3
15% of 20 is 3.
ANSWER:
m = -3/4
b = -3

STEP-BY-STEP EXPLANATION:
We have that the equation in its slope-intercept form is the following:

We calculate the slope as follows:

To calculate the slope we use the intercepts that are (-4, 0) and (0, -3), we replace:

Now, the value of b would be -3, since the y-intercept is (0,-3), therefore, the equation would be:
The correct answer is 4/3
