In the first problem M bisects like AB. Because one side is thirteen we know the other side is too. So in total the line is 26. The ray MC bisects the line AB in line two. One side is eight so the other is eight. The line in total is 16

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
