The equation y = 3x + 8 models the amount of snow in inches(y) after x hours.

Interpret the y-intercept

• 8 inches of snow falls in 3 hours.

• 3 inches of snow falls in 8 hours.

• When we started measuring, there were already 8 inches of snow on the ground.

• Every hour, 3 new inches of snow accumulates.

Chris collects shoes. The equation y =3x + 122 models the number of pairs of Jordans(y) he has in his collection after x months.

Interpret the slope.

• Chris collects an additional 3 pair of Jordans each month

• Chris collects 122 pairs of Jordans every 122 months

• In 3 months, Chris will have 122 more pairs of Jordans.

• Chris sells 3 pairs of Jordans for $122 each.
