Relating Equations, Graphs, Tables

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

At 10:00 pm, there was already 8.6 inches on the ground. If it is to snow 2 inches per hour after, what equation could be used to model the situation after x amount of hours.

• y = 2x + 8.6

• y = 2x - 8.6

• y = -2x + 8.6

• y = 1/2x + 8.6
