Question

What point is the y- intercept
(4,0)
(0,2)
(2,0)
(0,4)

Answer 1

the y intercept is always where x is 0. Since your graph is crossing where y=2, then your y intercept is at (0,2)

Answer 2

The y intercept represents the point in which the line cut the axe Y'Y, when x=0.
As you can see on the graph, the line is intercepting with axe Y'Y in y=2. Which means that the coordinates of the y-intercept are (0,2).
