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

This is a linear equation of the form:
y = mx +b

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

We can see that m = 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.
