• Graph B, C and D only

• Graph A only

• All of the graphs represent functions.

Which has a positive slope?

• Only Function 1

• Only Function 3

• Both functions 1 & 3

• Both functions 2 & 3

Which function has a greater y-intercept, and why?

• Function 2 has a greater y-intercept because 5 > 3.

• Function 1 has a greater y-intercept because 5 > 3.

• Function 2 has a greater y-intercept because -1/2 > -3.
