Answer
y = (1/2)x
Work Step by Step
y intercept at origin (0,0)
slope (m) = 1/2 which is a positive slope (remember rise/run)
start at origin (0,0) and count 1 square up and 2 squares to the right. Then at the origin (0,0) and count 1 square down and 2 squares to left. Connect the 3 dots to make a straight line
