How to Find Slope from Graph. Tutorial, Examples , Practice Problems

Video Tutorial on Finding Slope from The Graph

Example 1

Find the slope of the line in the graph below

Step 1

Plot and label 2 points on the line, anywhere on the line. Remember that the slope of a line never changes, so you can choose whatever 2 points you want and you will always get the same slope.

Step 2

Calculate the rise and run (You can draw it on the graph if it helps).

Step 3

Use the slope formula.

The slope is 2/4, which , of course, you can simplify to ½.
