Slope y=mx proportional

Front

Back

The slope (m) represents the rate of change of y with respect to x.

Front

Define a proportional relationship in terms of slope.

Back

A proportional relationship has a constant slope that passes through the origin (0,0).

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

What does it mean if a graph is nonproportional?

Back

A nonproportional graph does not pass through the origin and has a varying slope.

Front

Back

The slope is 2.

Front

If a line has a slope of 0, what does that indicate?

Back

A slope of 0 indicates a horizontal line, meaning y does not change as x changes.

The slope is -2.
