Front

How do you find the slope of a line from a graph?

Back

The slope can be found by calculating 'rise over run', which is the change in y divided by the change in x.

What does the y-intercept represent in a linear equation?

Front

How can you determine the y-intercept from a graph?

Back

You can determine the y-intercept by looking at where the line crosses the y-axis.

Front

If a line has a slope of -1, what does this indicate about the line's direction?

Back

A slope of -1 indicates that the line descends from left to right.

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables.
