Question

Please help I’m vvv confused

Answer 1

y=kx

y=k(7)x

y=7x(11)

y=7*11

y=77

Explanation:

So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

Answer 2

Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result

x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check 2×7=14, 11×7=77

Answer: k=7, y=7x
