To go to the park, it costs $4 plus $3 per child. Which equation shows this situation, where x represents the number of children?

• y=4x+3

• y=3x-4

• y= -4x+3

• y=3x+4

Function A is represented by the table. Function B is represented by the equation y = 3x - 4. Which function has the greatest rate of change?

• Function A because it has a rate of change of 1/2 and Function B has a rate of change of 1/3.

• Function B because it has a rate of change of 3 and Function A has a rate of change of 2.

• Function B because it has a rate of change of -4 and Function A has a rate of change of -10.

• Function A because it has a rate of change of 10/7 and Function B has a rate of change of 3.
