Answer:

y=-3x+5

Step-by-step explanation:

1. Put the equation into point-slope form: y-y1=m(x-x1)

Use the coordinates to put into y1 and x1 and use the slope to put into m. For y1 and x1, whenever there's a negative number in the provided coordinates, you'll need to change the subtraction sign into an addition sign because two negatives make a positive.

y+1=-3(x-2)

2. Distribute -3 to x-2 and subtract 1 from both sides.

y+1=-3x+6

y=-3x+5
