1. What is a linear relation?

A single fixed number A shape with four equal sides A type of fraction A rule that connects two sets of numbers, usually x and y

2. Using the rule y = 3x + 2, what is y when x = 2?

8 6 7 9

3. What is the ordered pair for x = 1 using the rule y = 3x + 2?

(1, 3) (1, 5) (0, 2) (1, 2)

4. When you plot several ordered pairs from a linear relation on a Cartesian plane and connect them, what shape do they form?

A circle A curved wave A straight line A random scatter with no shape

5. What does the point where two lines intersect on a graph represent?

The solution where both equations have the same x-value and y-value A random, meaningless point The starting point of both lines only The end of the graph

6. Look at these tables of values for two lines: Line 1: (0,1), (1,2), (2,3), (3,4). Line 2: (0,5), (1,4), (2,3), (3,2). At which point do the two lines cross?

(0, 1) (1, 2) (2, 3) (3, 4)

7. Two market stalls charge different rates. Stall A charges a flat GHC 10 plus GHC 2 per item. Stall B charges GHC 4 per item with no flat fee. Which equation represents Stall A's total cost, y, for x items?

y = 2x y = 4x y = 2x + 10 y = 10x + 2

8. Using the same two stalls (Stall A: y = 2x + 10, Stall B: y = 4x), at how many items, x, will both stalls cost the same amount?

x = 2 x = 10 x = 20 x = 5

9. If two lines on a graph are perfectly parallel and never cross, what does this tell you about the solution to their equations?

There are infinitely many solutions There is exactly one solution The solution is always (0,0) There is no solution, since the lines never meet
