Hey there!
2(3x - 7) = 9y
2(3x - 7) = 9(-7)
2(3x - 7) = -63
2(3x) + 2(-7) = -63
6x - 14 = -63
ADD 14 to BOTH SIDES
6x - 14 + 13 = -63 + 13
SIMPLIFY IT!
6x = -63 + 13
6x = -49
DIVISION 6 to BOTH SIDES
6x/6 = -49/6
SIMPLIFY!
x = -49/6
x = -8 1/6
Therefore, the answer should be:
x = -8 1/6 (or x = -49/6 [EITHER OF THOSE SHOULD BE YOUR RESULT BECAUSE THEY ARE BOTH EQUAL TO EACH OTHER])
Good luck on your assignment & enjoy your day!

2 bc u just do change in y over the change in x. Start from a point and go down then go to the left.
A quadratic equation is one in which the highest exponent of x is 2.

is quadratic; the highest exponent is 2.
x³-3x²+1=0 is NOT quadratic. The highest exponent of x is 3, not 2.
5x-7=0 is NOT quadratic. The highest exponent of x is 1, not 2.
x²+3x-5=0 is quadratic; the highest exponent of x is 2.
x-5=9x+7 is NOT quadratic. The highest exponent of x is 1, not 2.
x²-x=3x+7 is quadratic; the highest exponent of x is 2.
