Stephanie says of the graph of y is equal to 3x +2 and why is it going to 3x -2 are parallel. isabella says the grass are perpendicular who is correct? explain your reasoning

Parallel because the Y moved 4 units down and the slope hasnt changed

By the Pythagorean Theorem:

h^2=x^2+y^2

Which just means that the hypotenuse (longest side) squared is equal to the sum of the side lengths squared...in this case:

h^2=5^2+13^2

h^2=25+169

h^2=194

h=√194

h≈13.93 in (to nearest hundredth of an inch)

Mckensey is correct as shown above.

Cara's mistake was in letting c be a side length instead of the length of the hypotenuse...
