Answer:
x = {-10, 10} (Algebraic)
Step-by-step explanation:
Simplifying
4x2 = 400
Solving
4x2 = 400
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.
x2 = 100
Simplifying
x2 = 100
Take the square root of each side:
x = {-10, 10}
The standard form for y=-7+6x is Ax + By = C
It would be no!
because when you draw a line multiple points go thru it.
hope this helped!

Okay uh
x = 2y + 9
14x + 2y = - 54
14x + 2y = - 54
14(2y + 9) + 2y = - 54
28y + 126 + 2y = -54
30y + 126 = -54
- 126 -126
30y = -180
30y/30 = -180/30
y = -6
x = 2y + 9
x = 2(-6) + 9
x = -12 + 9
x = -3
(x, y) = (-3, -6)
