LT 1C: I can solve an equation for a given variable.
Josh is talking on the phone to his friend Greg who lives in Europe. Greg is used to
describing temperatures in °C, while Josh is used to describing temperatures in °F.
Greg can use the formula above to quickly convert the temperatures Josh describes to °C.
Rewrite the formula in terms of F so that Josh can quickly convert the temperatures that
Greg describes to °F.
LT 2B: I can apply and model with function notation.
WRITE YOUR ANSWER IN FUNCTION NOTATION.
LT 2B: I can apply and model with function notation. MAKE SURE YOUR ANSWER IS IN FUNCTION NOTATION.
LT 2C: I can use function notation to graph functions.
Directions: Complete the table of values to help you graph the following function.
LT 3A: I can determine the rate of change and slope in linear relationships.
Find the rate of change represented in this table of values. Simplify.

Range | arrow_right_alt | A relation in which every domain value is paired with exactly one range value. |
Input | arrow_right_alt | A function that does not form a straight line when graphed. |
Independent Variable | arrow_right_alt | A test used to determine whether a relation is a function. If any vertical line crosses the graph of a relation more than once, the relation is not a function |
Domain | arrow_right_alt | A value that is substituted for the independent variable in a relation or function |
Non-Linear Function | arrow_right_alt | The result of substituting a value for a variable in a function. |
Relation | arrow_right_alt | The input of a function; a variable whose value determines the value of the output, or dependent variable. |
Vertical Line Test | arrow_right_alt | A function that can be written in the form f(x)=mx + b. Its graph is a straight line. |
Dependent Variable | arrow_right_alt | A set of ordered pairs. |
Linear Function | arrow_right_alt | The set of all second coordinates (or y-values) of a function or relation. |
Function Notation | arrow_right_alt | The set of all first coordinates (or x-values) of a relation or function. |
Output | arrow_right_alt | The output of a function; a variable whose value depends on the value of the input, or independent variable. |
Function | arrow_right_alt | If x is the independent variable and y is the dependent variable, then the function notation for y is f(x) , read “f of x,” where f names the function. |

Slope-Intercept Form | arrow_right_alt | A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable. |
Run | arrow_right_alt | A measure of the steepness of a line. |
y-intercept | arrow_right_alt | y = mx + b, where m is the slope and b is the y-intercept |
Rise | arrow_right_alt | Ax + By = C, where A, B, and C are real numbers and A and B are not both 0. |
Slope | arrow_right_alt | The x-coordinate(s) of the point(s) where a graph intersects the x-axis. |
Standard Form | arrow_right_alt | The y-coordinate(s) of the point(s) where a graph intersects the y-axis. |
x-intercept | arrow_right_alt | The difference in the y-values |
Rate of Change | arrow_right_alt | The difference in the x-values |
