What is the slope of the line threw (-9,6) and (-3, 9)

The slope is the change in Y over the change in X.

(-9,6) is X1 and Y1.

(-3,9) is X2 and Y2.

Slope = Y2-Y1 / X2-X1

Slope = 9 - 6 / -3 - (-9)

Slope = 3/6 = 1/2

The slope = 1/2

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
