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)
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
Find the slope of the line in the diagram below:
-1/10 = -0.1
Find the slope between the points (5, 3) and (-2, 8)
-5/7 = 5/-7
What is the rate of change for the function shown below:
What is the rate of change for the function representedIn the table?
X -2 -1 0 1Y -3 -1 1 3
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?
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
Write an equation in slope-interceptform for the graph shown:
State the x-intercept and y-intercept of the graph below:
X-int. = 6
Y-int. = -9
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
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.
Solve the system of equations by graphing:
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
Solve the following system of equations by substitution:
X = -4 and Y = -8
Solve by substitution:
(x, y) = (4, -7)
