y = 30 + 12.5x

Front

What is the slope (m) in the equation y = mx + b?

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the standard form of a linear equation?

Back
