9/23 Objective

I will be able to identify and represent patterns that

describe linear functions.

LINEAR FUNCTION

• function whose graph is a line

• exponent of x will be 1

• has a constant rate of change

Makes when graphed:

Line

Parent Function

y = x

Standardform:

Ax + By = C

Slope-Intercept

form:

y = mx + b

FUNCTION

relationship that pairs each

input value with exactly one

output value (input cannot repeat;

output can repeat)

9/24 Warm UpSolve the equation you wrote on Wednesday to answer the question.

A plumber finished three jobs on Tuesday.

The first two only cost the owner the $45 trip fee because they took very little time to complete.

For the third job, the plumber charged the trip fee plus 6 times his hourly rate.

If the plumber received a total of $303 for the day, what is the hourly rate?

9/24 ObjectiveI will be able to solve and

graph inequalities containing the words “and”

and “or”.
