Answer:
y = 8.5x -2
Step-by-step explanation:
Hi there,
The slope intercept equation basically says this.
y = mx+b
b = the y intercept(aka where the line crosses the y axis)
m = slope
now here the slope is as x increases by 5, y increases by 42.5. then set up a proportion, do the problem, or use a calculator. 42.5 divided by 5 = 8.5 which means for everyone 1 unit x increase by, y also increases by 8.5.
finally just put a x there, signifying how many x's. it makes pretty much logical sense
