Question

Fred is on a diet. He currently weights 249 pounds. He loses 5 pounds per month.

Write a linear equation.

Answer 1

y= -5x+249

Explanation:

1. A linear equation is y=mx+b, with m=slope and b= y-intercept.

2. Since Fred is currently 249 pounds, the y-intercept is that number.

3. If he looses 5 pounds per month, than he looses -5x pounds, with x being the number of months.

4. So, y=-5x+249. This reads as: Fred's weight (the y=) is equal to his current weight minus 5 pounds for every month he looses weight.
