Jordan is saving money to buy a new Labubu! Camila gave him $7 and will give him $6.70 every day for walking her dog. Write an equation that represents this scenario.

y = 6.7x + 7

100

Solve this system 

2x + 3y = 13

4x − 3y = 5


x = 3 and y = 7/3 or (3, 7/3)

100

Which table is a function?

4 is a function

100

In slope-intercept form write the equation for:

y = 2/3x - 4

Maddie earns $8 per hour playing video games as a beta tester. Maddie was also paid just for attending. At the end of the day, Maddie had made $70. In slope-intercept form, write the equation that represents this scenario. Include what x must equal to be true. 

70 = 8x + 6

x = 8

Determine whether (2,3) is a solution to the system

          −x + y = 1

           3x + 2y = 12

Yes, (2,3) is a solution!

200

Which graph is a function?

(1) is a function since it passes the vertical line test 

200

What is the relation?

The relation of the table is

{(0,1), (1,2), (2,4), (3,16)}

Hannah is paying for swim lessons. The cost for the first lesson is $10, and she pays $7 per hour of swim time. In slope-intercept form, write an equation that represents this scenario.

y = 7x + 10

300

Solve by graphing

y = -2x + 3

y = -2x - 2

No Solution!

300

Which mapping diagram is not a function?

B is not a function because the C input has two outputs.

300

Write the Domain and Range for the following mapping diagram:

Domain: { -4, -3, -2, 0, 4, 5 }

Range { 0, 2, 5, 6, 11 }

How many biological children does Jordan have?

Zero

400

Solve for x:

2(x−3) + 4 = 3x−5

x = 3

400

Solve this system

2x+3y=8

6y+4x=16

Infinitely Many Solutions

400

Is the inverse of this relation a function?

{(6,0), (7,1), (6,2), (5,3), (3,5)}

Yes, the inverse relation: 

{(0,6), (1,7), (2,6), (3,5), (5,3)}

has one value of y for every x value so it is indeed a function!

400

Create a table and mapping diagram for the following relation: { (4,20), (5,30), (6,42), (7,56) }

Yes!
