You have a dog walking business. You charge based on the weight of the dogs. For a 45-minute walk your prices are: • For dogs that weight 0 to 15 lbs. you charge $5.00.
• For dogs between 15 lbs to 45 lbs. you charge $7.00
• Dogs over 45 lbs. you charge $9.00.

Define the variables:

Write a piecewise function for the dog walking business, including a conditional statement for the variables.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the correct option is b
