Question

Anyone please...Explain & solve

Answer 1

y = -2x

Explanation:

General formula for direct proportion: y = kx, where k is the constant of proportionality. If y = 10 when x = -5, then 10 = -5k, and k = -2.

Then the desired relationship is y = -2x.

Answer 2

y = -2x

Explanation:

We have direct variation means

y =kx

We know y and x

10 = k (-5)

Solve for k by diving by -5

10/-5 = k (-5)/-5

-2 = k

y = -2x
