• The student didn't make a mistake

• Both Options 1 and 2

Please find the value of Y when x equals 1 to complete the table.

Please find the value of Y when x equals 3 to complete the table.

Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 5

The point where the line crosses the y-axis is called the:

• origin

• x-intercept

• y-intercept

• slope

Jackson started with $800 in his savings account, but has to pay $30 a month for his electricity bill. Write an equation that relates his savings, y, to the amount of months, x.

• y = -30x + 800

• y = 30x - 800

• y = -30x

• y = 12x - 30

Stephanie owes her mom $80 for a recent trip to the mall. She plans to payback $15 a month until it is paid back. Write an equation in slope-intercept form that relates the amount she owes, y, to the amount of months, x.

• y = 15x - 80

• y = 15x + 80

• y = -15x + 80

• y = -15x - 80
