Question

Suppose y varies directly with x, and y = 8 when x = –6. What direct variation equation relates x and y? What is the value of y when x = –2?

Answer 1

y varies directly with x means \(\Large y=kx \)

Answer 2

where \(\Large k\) is known as the constant of variation

Answer 3

now you've got the equation
Substitute the value of x & y
y=8 & x=-6
NOw you have to find k

Answer 4

@Erin08 Did you understand / Can you do it ?

Answer 5

yes thank you very much!

Answer 6

After finding k

again substitute the value of x (x=-2) in the same equation (y=kx) {now you have value of k & x} and find y
