Answer:

-8/9

Step-by-step explanation:

To find the slope of a line using two points, the equation is y2 - y1/x2 - x1.

In this example,

y2 = -2

y1 = 14

x2 = 9

x1 = -9

Plug the points into the equation.

y2 - y1/x2 - x1

-2 - 14/9-(-9)

Next, simplify.

-16/18

-8/9

m = -8/9

Y=6/13X is a proportional relationship

Ivan

Answer:

x in (-oo:+oo)

Y = (6/13)*x // - (6/13)*x

Y-((6/13)*x) = 0

Y+(-6/13)*x = 0

Y-6/13*x = 0 // - Y

-6/13*x = -Y // : -6/13

x = -Y/(-6/13)

x = 13/6*Y
