Front

Write the equation in point-slope form of the line that passes through the point (-2, -1) with slope m = -3.

Back

y + 1 = -3(x + 2)

Front

What is the slope of the line represented by the equation y = (2/3)x + 1?

Back

Back

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

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