y = -2

y = -2x

y = x + 2

x = 12

y = 2x + 1

y = $$-\frac{2}{3}$$ x + 1

y = 0.5x - 2

y = -3x - 4

Jack earns $5 per day for walking the dog.

Cecil completed 5 math problems a day for four days.

Liliana got 20 balloons for her birthday, but 5 have popped each day that has passed since her birthday.

Deborah sells snacks for $5 each and adds the money to her bank account.

y = -5x - 4

y = 5x + 4

y = -4x - 5

y = 4x + 5
