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

Explanation:

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

See below

Explanation:

To graph the function using a table, pick a few numbers for xx 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 xx.

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

Then plot them.
