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

Front

How do you identify the slope from a graph?

Back

The slope is the ratio of the rise (change in y) to the run (change in x) between two points on the line.

What does the y-intercept represent in a graph?

Back

Front

If a line has a slope of 2, what does this indicate?

Back

A slope of 2 indicates that for every 1 unit increase in x, the value of y increases by 2 units.

Front

What is the significance of a negative slope?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship between the two variables.

How can you find the equation of a line given two points?

Back

The slope of the line is -3.

How do you convert a standard form equation to slope-intercept form?

Front

What does it mean if a line is horizontal?

Back

A horizontal line has a slope of 0, meaning there is no change in y as x changes.

Front

What does it mean if a line is vertical?

Back

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