Functions and Slope Quick Check

Randy must graph x + 3y > 6. Part of his effort is shown in the graph. Which of the following is true about Randy's work so far?

• All is great so far. He just needs to do the shading part.

• He has the incorrect y-intercept indicated since it should be at (0, 6).

• His "rise over run" technique is incorrect since it is reversed.

What is the name of the test that we do on a graph to see if it is a function?

• vertical line test

• horizontal line test

• there isn't a name for it

• slope line test

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
