Answer:
The function's graphic is the one that is below the first one in th right.
Step-by-step explanation:
If we want to know how much Chelsea earns for dogsitting her neighbours' dogs, we have to form a linear equation, that must have the following formula:
[tex]y= ax + b[/tex]
In this case, B is the constant value. We know Chelsea charges 12$ for dogsitting, and that doesn't depend on anything (B). But, if you want to Chelsea to walk your dog, then you'd to pay 2.50$ for each walk (X).
[tex]y= 2.50x + 12[/tex]
So, if Chelsea doesn't walk the neighbour's dog (x=0), she would be earning 12 dolars.
[tex]y= 2.50 x 0 + 12 = 12[/tex]
If she walks four times the dog, she would be earning:
[tex]y= 2.50 x 4 + 12 = 10 + 12 = 22 [/tex]
Knowing these two values, we can graph the equation. When x=0, y=12, and when x=4, y=22
The function's graphic is the one that is remarked in the attachment.
