Question

Answer 1

## Step 1: Find the slope### Let

represent the weight of the package and

represent the cost. We have two points:

and

. The slope

is given by

.## Step 2: Find the y-intercept### Using the point-slope form

with the point

and slope

, we have

. Simplifying, we get

, so

.
