Linear Equations : Slope of a Line Quiz
Quiz
*Theme/Title:
Slope of a Line
* Description/Instructions
The slope of a line is the number of units a line rises or falls for each unit of horizontal change. The formula for slope (m) is the following:
m = (y2 - y1)/(x2 - x1)
If the m > 0 (positive) the the line rises from left to right.
If the m < 0 (negative), then the line falls from left to right.
If the m = 0, then the line is horizontal.
If the m is undefined, then the line is vertical.
Example:
Determine the type of slope from a line that passes through points (-5, 6) and (-3, 10).
(10 - 6)/(-3 + 5) = 4/2 = 2
So m = 2, therefore the line rises from left to right.
For the following problems, you will determine the type of slope. Your choices are as follows: Line rises from left to right, line falls from left to right, line is horizontal, or line is vertical. You will need a scratch sheet of paper and a pencil. Select the best answer from the choices.
