Question

How do you graph `y=3x` using a table?

Answer 1

graph{3x [-10, 10, -5, 5]}

Explanation:

this function is in the form of `y=mx+q` with `m=3, q=0` so it's an straight line: ascending [`m>0`], that touch the `y` axis in the point `(0,0)` [`q=0`]

Answer 2

See below

Explanation:

To graph the function using a table, pick a few numbers for `x` and evaluate y to get a bunch of ordered pairs. It's good practice to pick a few negative numbers, zero and a few positive numbers for `x`.

x | y
-3 | -9
-2 | -6
-1 | -3
0 | 0
1 | 3
2 | 6
3 | 9

Then plot them.
