Write the equation of the line of reflection​

y=-1

Step-by-step explanation:

Since we see an overlap, the line must cross through the original image.We can solve the equation of the line of reflection by realizing there is no slope because the reflection is parallel to the x-axis.

A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.

b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.

c) f(x) = 2.69 + 0.48(x-1)

d) domain is the x values; range is the y values
