Write the slope-intercept form of the line with a slope of -3/4 containing the point (8, 2).

Back

y = -3/4x + 8

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

Front

What is the general form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

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 a line of best fit?

Back

A line that best represents the data on a scatter plot.
