#### Answer

Graph 4

#### Work Step by Step

To match a graph with an equation you want to check the slope and the y-intersect.
Our equation has the slope m=2 (the number x is multiplied by) and the y-intersect 1 (you can calculate this by setting x equal to 0.
Graph 4 is the only line that has an y-intersect at 1 and has a positive slope.
