Is this linear or nonlinear? if linear you will need to write a function that models is a then write one order pair. charlie is getting a book printed. it costs $7 plus $0.50 for each page added.

I think the equation can be written as 7.00+.50x=

Because it cost $7.00 and it says it is .50 for each page. I goes starts at 7.00 and goes up .50 each time. So the equation is linear.

X. Y

1, 7.50

2, 8

3, 8.50

step-by-step explanation:

the first one, all those points on the line just make a strait line.
