Answer 2

you rented a book from the library for 2 dollars. if you do not return the book before the due date you have to pay .75 cents each day its late. explain why this can be modeled by a linear equation?

Answer 3

okay, because you only have one variable right? only one thing that can change, which is the amount of days its late. So you can simply set up a variable, you have a constant 2 dollars, and .75 cents x amount of days. So you set up the equation

Answer 4

A quadratic equation can only one variable, but it's not linear.

Answer 5

One reason it's linear is because for every value of x there is a value of y that when graphed forms a straight line.

Answer 6

this is the linear equation y=.75x+2. i want to know WHY this can be modeled as a linear equation

Answer 7
