Question

Suppose why very directly with X write a direct variation equation that relates X and Y. Y=-10 when x=2

Answer 1

In this case, the direct variation equation that relates X and Y can be written as:

Y = kX

To find the value of k, we can use the given information: Y = -10 when X = 2.

-10 = k(2)

To solve for k, we divide both sides of the equation by 2:

-10/2 = k

k = -5

Therefore, the direct variation equation that relates X and Y is:

Y = -5X
