charges a fee of $31.75 plus $4.00 per day to rent the same car. Use a graphing calculator, find the number of days for which the costs are the same. Round your answer to the nearest whole day.

Can someone solve this and explain how?

And also these,

**Solve the system by graphing.**

3. {y=-x-9

{3x-y=-11

4. {-0.2x-0.8y=0

{0.7x-0.1y=-2.9

5 {-2x+3y+4=0

{6x-9y=-2

Without graphing, classify each system as independent, dependent, or inconsistent.

{-x-y=-2

{3x-3y=6

{y=2x-7

{4x-2y=14

{8x+2y=0

{y=-4x+2
