ANSWER and EXPLANATION
We have the equation:
y = 3x
To be able to graph the equation, we have to first find the values of y for each of the values of x.
When x = -1:
y = 3(-1)
y = -3
When x = 0:
y = 3(0)
y = 0
When x = 1:
y = 3(1)
y = 3
When x = 2:
y = 3(2)
y = 6
When x = 4:
y = 3(4)
y = 12
Now, we graph it:
A line
