Answer:

Part A) the direct variation equation that relates x and y is:

$y= -5x$

Part B) value of y = 75

Step-by-step explanation:

Part A)

We are given that y varies directly with x, and y=10 when x=-2 what direct variation equation relates x and y?

If x and y are directly related then:

y ∝ x or y=kx

where k is constant of proportionality.

Now, finding k:

y=10 and x=-2

$y=k\,\,x\\10=k*-2\\k=10/-2\\k=-5$

So, value of k = -5

So, the direct variation equation that relates x and y is:

$y= -5x$

Part B)

What is the value of y when x = -15

the equation is:

$y= -5x$

Putting x = -15

$y=-5x\\y=-5(-15)\\y=75$

So, value of y = 75
