Aspider is climbing on a wall. it starts at point a, moves straight up 15 inches, to the right 7 inches and then straight down 6 inches to stop at point b. if m represents the midpoint of ab, then find the coordinate that represents m.

Let x coordinate represent movement left-right and y coordinate represent movement up down.

We start at A(0,0).
Straight up -> (0,15)
Right -> (7,15)
Straight down -> (7,9)

We have B(7,9)

To find midpoint we use formula:

1. Add 4 to each side of the equation:

2. Divide both sides of the equation by 3:

3.Take the log of each side:

4.Use the Exponential Property and write in decimal form:

5.Divide each side by log 2:

6.Find the value of  and substitute:

7. Add 5 to each side of the equation:

8. Simplify:
