Answer:
(0,0)
Step-by-step explanation:
To find the y-intercept of a graph, you need to make x = 0 and then solve the equation for y.
In this case we have g(x) = 3x. This can also be written as y = 3x
So we're going to make x = 0 and solve for y:
[tex]y=3x\\y=3(0)\\y=0[/tex]
Thus, the y-intercept of the graph is (0,0)
