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:
