Question 253392
in a graph with the points (-5,10) (3,y) and the slope=-(3/8) I need to solve for y
.
slope, given two points:
m = (y2 - y1)/(x2 - x1)
.
The problem gives us:
m = -3/8
(x1,y1) as (-5,10)
(x2,y2) as (3,y)
.
Plug the given info into:
m = (y2 - y1)/(x2 - x1)
we get
-3/8 = (y - 10)/(3 - (-5))
-3/8 = (y - 10)/(3 + 5)
-3/8 = (y - 10)/8
Multiplying both sides by 8:
-3 = y - 10
7 = y
