What is the equation of the line that contains the two points (0,-1) and (-1, -3)?

Step-by-step explanation:

y=2x-1.

Use the formula y2-y1 over x2-x1. Plug in your digits. (0,-1) and (-1,-3). So you put in -1-0 and get -1 as x. For y plug in -3-(-1) and get 2 as x. A formula for a slope intercept is y=mx+b. So y=2x-1.

#1 whats the other brand lol

#2
