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

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

#### Explanation:

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

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.
