Question 1

In this hanger, the weight of the triangle is x and the weight of the square is y.
Write an equation using x and y to represent the hanger.

Question 2

In this hanger, the weight of the triangle is x and the weight of the square is y.
If x is 6, what is y?

Question 3

Question 4

Andre and Diego were each trying to solve 2x + 6 = 3x - 8. Describe the first step they each make to the equation.

The result of Andre’s first step was -x + 6 = -8.

Question 5

Complete the table with values for x or y that make this equation true: 3x + y = 15.

Create a graph, plot these points, and find the slope of the line that goes through them.

Question 6

Select all the situations for which only zero or positive solutions make sense.

The number of students remaining in school after 6:00 p.m.

The elevation above sea level of a hiker descending into a canyon.

Measuring temperature in degrees Celsius at an Arctic outpost each day in January.

A bank account balance over a year.
