What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is and the direction it goes (positive slope goes up, negative slope goes down).

What does it mean if a line has a slope of 0?

Back

If a line has a slope of 0, it means the line is horizontal and does not rise or fall as it moves along the x-axis.

Front

What does it mean if a line has an undefined slope?

Back

An undefined slope occurs when a line is vertical. This means that the x-value does not change, and the line goes straight up and down.

How do you graph a linear equation?

Back

To graph a linear equation, first plot the y-intercept on the y-axis, then use the slope to find another point. Draw a straight line through these points.
