Work Step by Step

RECALL: The function $y=mx+b$ or $f(x) = mx+b$ has m = slope and b = y-intercept. Thus, the given function has: slope = 2 y-intercept = 1 To graph this function, perform the following steps: (1) Plot the y-intercept point $(0, 1)$. (2) From the y-intercept, move 2 units up (the rise) and 1 unit to the right (the run). These movements lead to the point $(1, 3)$. (2) Connect the two points together using a line to complete the graph. (refer to the attached image in the answer part for the graph)
