Question

How do you graph `y=1/2x-6`?

Answer 1

`1/2` is the slope, `-6` is the `y`-intercept.

For graphing a line you need two points.

Step 1: use the `y`-intercept, where `x=0`,
now you have point `(0,-6)`

Step 2: Take any other `x` and find the `y`, say `x=10`
now you have point `(10,-1)`

Step 3: draw the line:
graph{0.5*x-6 [-16.02, 16.01, -8.01, 8.01]}
