8.F.B.4

Which statements are used to describe "slope?"

• Rise over run.

• The change in x over the change in y.

• The change in y over the change in x.

• A negative slope means the line is backwards.

• The steeper the slope, the greater the slope value.

Select the true statements about slope.

• The change in x and y is found by adding the coordinate point values.

• The slope is a unit rate.

• A slope of $\frac{-6}{-4}$ describes a line that increases.

• $x_1$ and $x_2$ are exponents.

• The slope formula is $\frac{x_2-x_1}{y_2-y_1}$
