Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the ratio of the rise (vertical change) to the run (horizontal change).

Front

How do you find the slope using rise/run?

Back

To find the slope using rise/run, identify two points on the line, calculate the vertical change (rise) and the horizontal change (run), and then divide rise by run.

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

In the equation y=mx+b, what does 'm' represent?

Back

'm' represents the slope of the line.

Front

In the equation y=mx+b, what does 'b' represent?

Back

'b' represents the y-intercept, the point where the line crosses the y-axis.

Front

What is the y-intercept of the line with the equation y=-2x+4?

Back

The y-intercept is 4.

Front

How can you determine the y-intercept from a linear equation?

Back

The y-intercept can be determined by setting x=0 in the equation and solving for y.

Front

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

Back

The slope is 2.

Front

If a line has a slope of 0, what does that indicate?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that indicate?

Back

An undefined slope indicates that the line is vertical.
