$m=-3/4; b=3 $
Work Step by Step
We need to put this equation in slope intercept form: y=mx+b. To do this, we need to isolate y. Thus, we first subtract each side by 3x to obtain that 4y=-3x+12. We then divide both sides by 4 to get that y=-3/4x+3. This is in the form y=mx+b, so we see that the slope is -3/4, and the y-intercept is 3.
