Based on the table below, this is the number of cups of yogurt that can be made with 3 gallons of milk.
milk (gal) | yogurt (cups) |
0 | 0 |
1 | 14 |
2 | 28 |
3 | 42 |
4 | 56 |
What is 42?

Make a table for when y = -1.5x + 4 and x = 1, 2, 3, 4.
-2, -0.5, 1, 2.5
A graph shows a picture of the relationship between this number of variables.
What is 2?
A function rule that could represent, for instance, this table:
x | y |
0 | 50 |
1 | 49 |
2 | 48 |
What is y = 50 - x
A function rule using x and y to represent the following ordered pairs: (0,3), (1, 4), (2, 5), (3, 6)
What is y = x + 3
A function rule using x and y that fits these ordered pairs: (0,-1), (1, 4), (2, 9), (3, 14)
What is y = 5x - 1
Find when for x= -5 for y = 2x - 3
2(-5) - 3 = -13
