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

Back

Use the formula m = (y2 - y1) / (x2 - x1).

What is the rate of change in a linear function?

Back

The rate of change is the slope of the line, indicating how much y changes for a unit change in x.

What does it mean if a line is horizontal?

Back

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

What does it mean if a line is vertical?

Back

A vertical line has an undefined slope, meaning x does not change as y changes.

How do you solve the inequality 2x - y < 6 for y?

Back

Rearrange to y > 2x - 6.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).
