How do you graph f(x)=(1/2)x ?

This is a linear equation of the form:
$y = m x + b$

$m$ is the slope and $b$ is the y-intercept.

We can see that $m = \frac{1}{2}$ and $b = 0$, which means this a line with positive 1/2 slope that passes through the origin.

We place a point at the origin. Then we count 1 unit in the positive y direction (rise) and 2 units in the positive x direction (run) to arrive at point (2,1). If we go in the negative directions, we'd arrive at (-2, -1).

A similar process can be used to find more points until a line can be drawn.
