Question

For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept.

Answer 1

For the y-intercept, substitute x=0 -> y = -2(0) - 3 -> y = -3

For the x-intercept, use the re-written equation:

x = (-y - 3)/2 -> set y=0 -> x = (-0 - 3)/2 -> x = -3/2

Answer 2

So, y-intercept: (0, -3)

x-intercept: (-3/2, 0)

Answer 3

so I don't graph anything?

Answer 4

You wouldn't have to graph, but I can draw you a graph.

Answer 5

so basically all im doing is substituting x and y with 0?

Answer 6

Yes that's correct. The second substitution is slightly harder.
