Answer 4

y = kx
7.5=(1.5)*k

k=5

Answer 5

so the direct variation equation is 7.5=(1.5)*k

Answer 6

bry856 has shown that k = 5 after solving y = kx for k

So y = kx turns into y = 5x when you replace k with 5

Answer 7

y = 5x

y = 5*1.5 ... replace x with 1.5

y = 7.5

so the equation checks out

Answer 8

thank you soo much I understand now.
