3-111.

This problem is a checkpoint for writing linear equations from multiple representations. It will be referred to as Checkpoint 3.

Write a linear equation that represents each situation.

1. An equation for the line below.

2. An equation for a line perpendicular to the line at right and passing through the point $(-1,-3)$.

3. An equation of the line passing through the points $(4,3)$ and $(-1,1)$.

4. At the concert, Elite Parking charges $\15$ for the first hour and $\7$ for each additional hour of parking. Write an equation to represent the cost $(C)$ for parking $(t)$ hours.

Check your answers by referring to the Checkpoint 3 materials located at the back of your book.
