How does the length of the hypotenuse in a right triangle relate to the lengths of the legs?
STALIN [3.7K]
It holds the legs up. there is a right angle which is the little box in the 90 degree corner:) the hypotenuse is always the longest part on the triangle which you can not simplify:) so the right triangle has legs that you can simplify:)

Which of the following coordinates is a solution to the linear equation?
Dima020 [189]
Right this is pretty simple all you do is sub the points to the equation given.
So first try the first point (2,-1) in y=-3x+7
==> -1=-3(2)+7
==>-1=1 this is not equal therefore not the right points

Then try (1,10)
==>10=-3(1)+7
==>10=4 this is incorrect therefore not the right points

Next try (3,-2)
==>-2=-3(3)+7
==>-2=-2 this is equal therefore this is the coordinates to the linear equation.

Finally try the last points to make sure you are correct.
==> -8=-3(-5)+7
==>-8=22 this is incorrect also.

Therefore the only coordinates that satisfies the equation is (3,-2)
