Answer
Refer to the graph below.
Work Step by Step
RECALL:
(1) The slope-intercept form of a line's equation is $y=mx+b$ where $m$=slope and $(0, b)$ is the line's y-intercept.
(2) The slope is the ratio rise (change in $y$) over run (change in $x$).
The equation $y=\frac{1}{3}x$ has a slope of $\frac{1}{3}$ and a y-intercept of $(0, 0)$.
The given function can be written as $y=x.$
This equation has a slope of $1$ and a y-intercept of $(0, 0)$.
To graph the equation, perform the following steps:
(1) Plot the y-intercept $(0, 0)$.
(2) Use the slope to plot another point.
From $(0, 0)$, move 1 unit up (the rise) and 1 unit to the right (the run) to reach $(1, 1)$. Plot $(1, 1)$.
(3) Complete the graph by connecting the points using a straight line.
