Slope of a Line Test
About Slope of a Line:

The slope of a line is a measure of its steepness. We calculate the slope of a line by comparing the change in y values (vertical change) to the change in x values (horizontal change) while moving along our line from one point to another.

Test Objectives:

•Demonstrate an understanding of the slope formula

•Demonstrate the ability to calculate slope using the slope formula

•Demonstrate the ability to calculate slope from the graph of the line
