Question

If g(x) = 3x is graphed on a coordinate plane, what is the y-intercept of the graph? 0

Answer 1

(0,0)

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:

`y=3x\\y=3(0)\\y=0`

Thus, the y-intercept of the graph is (0,0)
