I'm Sorry for all the work. I swear this is the last one! Please just help me in this last question.

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1), we have points (0,0) and (4,12)

m=(12-0)/(4-0)=12/4=3

y=3x+b, using point (4,12) we can solve for b

12=3(4)+b

12=12+b

b=0 so the line is

y=3x

answer: 94

step-by-step explanation: 79+91+92+94+94 = 450 divided by 5 (since there are 5 number that are being added) = 90
