Exploring Pythagorean Theorem & Graphing Linear Equations

A ladder is leaning against a wall. The foot of the ladder is 4 feet away from the wall, and the ladder reaches a height of 3 feet on the wall. Use the Pythagorean theorem to find the length of the ladder. Then, write the linear equation representing the relationship between the height of the ladder and the distance from the wall.

• The length of the ladder is 5 feet and the linear equation is h = sqrt(25 - d^2).

• The length of the ladder is 6 feet and the linear equation is h = 6 - d.

• The length of the ladder is 7 feet and the linear equation is h = d^2 - 4.

• The length of the ladder is 4 feet and the linear equation is h = 4 + d.

A baseball diamond is a square with each side measuring 90 feet. If you want to find the distance from home plate to second base, use the Pythagorean theorem. After finding the distance, write a linear equation that represents the relationship between the distance and the side length of the diamond.

• d = s + 90

• d = s/2

• d = s√2

• d = s^2
