What does the difference between each point on the graph tell us, in terms of our expression?
Constant rate of change, coefficient.
Evaluate 2a when a = 6. Show your substitution and work!
2(6) = 12
What is the coefficient in this expression: 10n
10
four times a number minus 7
4n - 7
Create a Table of values for the expression (10n + 2). Start with an input of 0 and continue up to an input of 5.
(0,2) (1,12) (2,22) (3,32) (4,42) (5,52)
Do these x,y coordinates form a linear relation?? Explain why!!
(0,4) (1,8) (2, 12) (3,20) (4, 12)
No - they are not changing at a constant rate - the points would not create a straight line.
Evaluate 6m - 2 when m = 15. Show your work.
6(15) - 2 = 90 - 2 = 88
What is the constant in this expression: a - 7
-7
The sum of a number plus twenty
Given the following values, what is the expression that relates to the table.
Input: 0 1 2 3 4 5
Output: 6 8 10 12 14 16
2n + 6
Is the following scenario Discrete or Continuous Data? Explain why.
You are driving to Vancouver from Calgary and measuring the time you've spent driving versus the distance travelled.
Continuous. There will be a distance correlated to each increment of time.
Evaluate 18n + 1 When n = 3
18(3) + 1 = 55
What is the variable and constant in this expression: 12m - 13
Constant = -13
Variable = m

You have $200. You went to the mall to buy n number of pants that cost
$5 each. Write an expression for how much money you will have left after buying n amount of pants.
200 - 5n
You go to the movies and pay $12 for the first movie. You must pay an additional $3 for every movie after that.
1) Write an expression for the total amount you would be paying if you watch n movies.
2) How much would it cost to watch 6 movies? Show your work!
1) 3n + 12
2) 3(6) + 12
18 + 12 = 30
$30
1) Write an expression for the following coordinates:
(0,3) (1,5) (2,7) (3,9) (4,11)
What is a real-life situation that could relate these coordinates and expression?
2n + 3
Answers will vary. Needs to be a situation that involves a constant term of 3 and a coefficient of 2.
Given the following coordinates:
(0,7) (1,8) (2,9) (3,10) (4,11)
Evaluate the expression that is represented by the coordinates when n = 30
n + 7
30 + 7 = 37
