Hope this helps and good luck :)
The slope of a line parallel to y= 5x + 2
This is because a parallel line will have the same slope as the line it’s trying to be parallel to. In this case, 5 :)

<u>Answer:</u>
A = 70
B = 90
<u>Step-by-step explanation:</u>
We know that Car A travels 20 mph faster than Car B.
Assuming the speed of Car B to be x and the speed of Car A to be x+20, we can write:

Taking the reciprocal of both sides to make x the subject:




---> speed of Car A
Finding the speed of Car B: 
Therefore, the speed of Car A = 70 and the speed of Car B = 90.
