Answer:

Step-by-step explanation:


Therefore, the equation of the line that goes through point (3, -2)and has slope ⅘ is

It is 71.4285% (to be exact) increase
proportional relational ship
y= kx
7 = k2
solve for k
7/2 =k
y = 7/2 x
if y = 21
21 =7/2 x
solve for x
multiply by 2/7 on each side
21* 2/7 = 2/7*7/2 x
6 =x
