Determine whether the relationship betweenthe two quantities described in each table is linear or not AND explain why.

X 1 2 3 4 Y 18.0 19.6 21.2 22.8

Yes, they have the same common difference (+1.6) 6

The table below shows the average rate of increase in a nurse’s salary over the past 20 years. Explain whether the growth in salary is linear.Year 1990 1995 2007 2012

Salary \$23,000 \$27,500 \$38,300 \$42,800

Yes…all the rates of change are the same 7

Find the slope of the line in the diagram below:

-1/10 = -0.1 8

Find the slope between the points (5, 3) and (-2, 8)

-5/7 = 5/-7 9

What is the rate of change for the function shown below:

−𝟔𝟒=−𝟑𝟐 10

What is the rate of change for the function representedIn the table?

Jimbo Jones spent \$46.50 on 3 T-shirts. The next time hespent \$31.00 on two T-shirts. What is the cost for one T-shirt?

\$15.50 12

State the slope and y-intercept for each equation:

Y = 5x – 1 y = 0.3x 3x + y = 6

Slope = 5

Y-int. = -1

Slope = 0.3

Y-int. = 0

Slope = -3

Y-int. = 6 13

Write an equation in slope-interceptform for the graph shown:

𝒚=𝟓𝟐 𝒙−𝟒 14

State the x-intercept and y-intercept of the graph below:

X-int. = 6

Y-int. = -9 15

State the x- and y-intercepts of the equation: 5x + 4y = -20, AND sketch the graph using the intercepts

x-int. = -4 y-int. = -5 16

Monty has a total of \$290 in ten and five dollar bills. This can be represented by the function 10x + 5y = 290. Interpret the x- and y-intercepts.

The x-intercept of 29 represents the number of \$10 billsThere would be if there were zero \$5 bills.

The y-intercept of 58 represents the number of \$5 billsThere would be if there were zero \$10 bills. 17

Solve the system of equations by graphing:

(-2, -2) 18

Julie has 81 pieces of jewelry.She has twice as many earrings as shehas necklaces. Create and solve a system of equations to find out how many earringsAnd necklaces she has.

x + y = 81Y = 2x

Solution: 27 necklaces, 54 earrings 19

Solve the following system of equations by substitution:

X = -4 and Y = -8 20

Solve by substitution:

(x, y) = (4, -7) What are you going to do to prepare for the Chapter 6 Test?
