Mercury · Answer

in y = mx + b form, m is the slope. therefore, for a slope of -3, your equation should have -3 before the x-value when written in y = mx + b form.

that narrows us down to choices A+B. it also tells us that the line passes through (−1, 6), so (-1,6) is a solution to the equation. plug in x = -1 and y = 6 into equation A, and see if both sides are equal. if yes, that's your solution, if not, repeat the same process with B.
