Answer:
y = -2x + 1
Step-by-step explanation:
To find slope, you need to use the formula:
m =
<u><em>Plug in the numbers accordingly:</em></u>
m =
m =
<u><em>Simplify:</em></u>
m = -2
<u><em>To find the y-intercept, you need to plug in one of the coordinates (doesn't matter which one) into the equation:</em></u>
Coordinate : (-1, 3)
3 = -2(-1) + b
3 = 2 + b
<u><em>Subtract 2 from both sides:</em></u>
3 = 2 + b
-2 -2
________
1 = b
<u><em>Put it all together:</em></u>
y = -2x + 1
