If y = 4x – 1, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

Hello!

To do this you will pick an x value, multiply it by the slope and add the y- intercept. Let's try 0.

y=4(0)-1
y=-1

So here, an ordered pair could be (0,-1)

We can try this again for different x-values.

y=4(1)-1
y=3

This gives us the ordered pair  (1,3)

y=4(100)-1
y=399

This would give us the ordered pair (100,399)

I hope this helps!

Yes, two vertical lines can be complementary
