No because if u count the corners there are 4 right angles
X=7 b/c you have to put all the x's on one side so you'll get -3x=-21 and you just divide by -3 and you get 7.
Answer and Step-by-step explanation:
The independent variable is m, and the dependent variable is h.
This is because you can plug in any value for m, making m NOT have to depend on any other value to become m.
With h, it needs the result of m and its other values to become the result of h. H relies/depends on the values in the equation to become a value.

You are shown an ordered pair with an x-coordinate of -5, so replace x with -5 and solve for y.
-3x + 7y = 5x + 2y
-3(-5) + 7y = 5(-5) + 2y
15 + 7y = -25 + 2y
5y = -40
y = -8
