52.63
Step-by-step explanation:
Answer:
1.5
Step-by-step explanation:
The constant of proportionality is the slope
m= (y2-y1)/(x2-x1)
Pick any two points
m = (12-6)/(8-4)
= 6/4
= 3/2
= 1.5
Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286
And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)
