Answer:
Step-by-step explanation:
The rate of change, slope, m is
m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so
m=(39-5)/(21-4)
m=34/17
m=2
So the rate of change is 2

Answer:
y=35x−9
Step-by-step explanation:
Step 1: Add -12x to both sides.
12x−20y+−12x=180+−12x
−20y=−12x+180
Step 2: Divide both sides by -20.
−20y−20=−12x+180−20
y=35x−9
