| Question | Answer |
| Is (2, 3) a solution to the equation y = 2x - 1 | y = 2x - 1 3 = 2(2) - 1 3 = 4 - 1 3 = 3 Yes |
| Is this relation a function? Explain why or why not . (0,1) (1,2) (2,3) (3,4) (4,4) | Yes, this relation is a function because every input has exactly one output. |

Fun+1 (binary/octet-stream)
|
Linear; Not a function |
| What are the input values? | The x values |
| What are the characteristics of a linear graph? | A straight line |
| How do you know if a GRAPH is a function? | It passes the Vertical Line Test |
| What are the output values? | The y values |
|

Fun+2 (binary/octet-stream)
|
Linear; Not a function |
| Is this relation a function? Explain why or why not. (-3,-1) (-2,0) (-1,3) (-1,0) (0,-1) | No, this relation is not a function because the ordered pair (-1,3) and (-1,0) have the same input but different outputs. |
| What does it mean to be a function? | Each input has only one output |

|
Nonlinear |
| What are the characteristics of a linear equation? | The equation has the variables in separate terms and all the variables have an exponent of 1 |
| What does the graph of a line with the equation y = 2 look like? | A horizontal line passing through the y-axis at (0,2) |
| Is this relation a function? Explain why or why not. (10,1) (11,6) (12,11) (13,16) (14,21) | Yes, this relation is a function because every input has exactly one output. |
| Is the following equation linear or nonlinear? x = 7 | Linear |
|

Fun+6 (binary/octet-stream)
|
Linear; Function |
| What are the output values in the following: {(1, 10); (2, 12); (3, 14)} | {10, 12, 14} |
| Is the following equation linear or nonlinear? y = -2x + 7 | Linear |
|

|
From x=0 to x=8 and from x=12 to x=20 |
| What are the characteristics of nonlinear in an equation? | The equation does not have the variables in separate terms or a variable has an exponent other than 1 |
| What are the characteristics of a linear table? | Both the x and y values change by a constant amount |
| Is this relation a function? If not, explain why. (-2,-2) (2,-1) (3,0) (5,3) (5,4) | No, this relation is not a function because the ordered pair (5,3) and (5,4) have the same input but different outputs. |
| What is the vertical line test? | A visual method of determining whether a graph is a function by visualizing whether any vertical lines would intersect the graph at more than one point or not |
| Increasing Linear Function | A function whose graph is a straight line that rises from left to right. |
| Is (3, 2) a solution to the equation y = 2x - 1 | y = 2x - 1 2 = 2(3) - 1 2 = 6 - 1 2 = 5 No |
| Decreasing Linear Function | A function whose graph is a straight line that falls from left to right. |
