Answer:

y = 3x-7

Step-by-step explanation:

Lines that are parallel have the same slopes.  

y = 3x-4  ---> y=mx+b (slope = m=3)

 

point-slope formula for a line:  y - y1 = m(x-x1)

 slope=m=3

(3,2)----> (x1,y1)

y - 2 = 3(x-3)

y - 2 = 3x-9

y = 3x-7

The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.
