Chapter 7 Review

List the ordered pair shown in the mapping diagram

• (0,0) (2,1) (4,1) (6,2)

• (0,0) (1,2) (1,4) (2,6)

• (0,0) (1,2) (2,6)

• (0,2) (1,4) (0,6) (1,2)

True or False. The mapping diagram shows a function.

• True

• False

Write the function rule for "The output is ten more than five times the input"

Tell whether the function is linear or nonlinear.

• Linear

• Nonlinear

Tell whether the function is linear or nonlinear.

• Linear

• Non Linear

Tell whether the function is linear or nonlinear

• Linear

• Non Linear

Find the slope and y intercept, then write the linear function (y=mx+b)

Interpret the slope for this situation

• 2 inches of snow falls per hour

• 1 inch of snow falls every 2 hours

Find the value of y when x = -3 in

y = -4x + 3

Find the value of x when y = 5,

y = -10x + 25
