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:

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.
