Answer:
y = 3x + 1
Step-by-step explanation:
(0,1) so that is the b
the rate of change is 9/3 so the m is 3
C Is The Correct Answer
47 degrees
Explanation:
your welcome
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
