Create Slope Intercept Given a Graph

Which equation represents the following graph?

• y = 3x + 2

• y = -2x + 3

• y = 2x + 3

• y = -3x + 2

Remember equations are written as y=mx+b. Create the equation by finding the slope from rise/run and the y-intercept by looking at where it crosses the y-axis.

You can also create an equation by making a List & Spreadsheet, Data & Statistics, Menu 4, 6, 1.

• A

• B

• C
