Answer:
y = 2x - 1
Step-by-step explanation:
(4,7) (2,3)
slope = (7-3)/(4-2) = 4/2 = 2
y = 2x + c
when x=4 , y=7
7 = 2(4) + c
c = 7-8 = -1
y = 2x - 1
The manger purchased 116 rolls of wallpaper. (5,568/48)
Multiple 10 on both sides to get m by itself
Simplify
7 = m

I can only guess what you're trying to do here.
suppose you started out with y = x^2. If you were to graph this, and then you were to move the graph 1 unit to the left and 2 units down, you'd have the graph of y = (x+1)^2 - 2.
