Answer:
x - 4 = 0 and x - 2 = 0
Step-by-step explanation:

The Pythagorean Theorem states that a² + b² = c², c being the hypotenuse.
Substitute known values into the equation.
7² + 2² = c²
49 + 4 = c²
c² = 53
c = √53
c = 7.28010989
Answer: The hypotenuse's length is 7.3 feet.
X values are increasing by 2
y values are increasing by 4
