first, we have to find the slope of the line using the slope formula: m = y2-y1/x2-x1
substitute: -3 + 1/2-0
then, solve: -2/2 = -1
so the slope (m) = -1
next, pick any point (i’m going to use (0,-1)) and plug that in along with the slop into the point slop formula: y-y1 = m(x - x1)
y + 1 = -1(x - 0)
then, just solve
y + 1 = -x + 0
y = -x -1
ANSWER: y = -x -1
