Interpreting Linear Functions

Front

Back

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

Front

Back

The y-intercept (b) is the value of y when x = 0.

Front

Back

Slope: 4, y-intercept: 1.

Slope: -3, y-intercept: 7.

Front

What does a positive slope indicate about a linear function?

Back

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

Front

What does a negative slope indicate about a linear function?

Back

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

Front

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

Back

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

Write the equation of the line with slope 2 and y-intercept 3.

For every 1 unit increase in x, y increases by 0.5 units.
