Question

For each direct variation, find the constant of variation. Then find the value of y when x=-5
y=2 when x=7

Answer 1

for direct varaition y=kx

Answer 2

when y=2 and x=7

Answer 3

so, 2=7x

Answer 4

*correction 2=7k

Answer 5

ya

Answer 6

so , k=2/7

Answer 7

so 7/2 ? but then how do you plug in the -5

Answer 8

So the direct varaiation equation is y = 2/7x

Answer 9

when x=7 y=2/7 so k=2/7*7=2
