Answer:
Step-by-step explanation:
remember that slope is change in y over change in x or (y2 - y1)/(x2 - x1)
so let’s look at two points (1,5) and (2,1)
(5-1)/(1-2)
4/-1
-4
the slope is -4
to find the y intercept, look where x = 0 and move up or down the y axis
in this case when x = 0, y is 5
so the y intercept is (0,5)
apply this to the second problem
