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 simplifty to ½.
