2x + 3y = -21
2x = -21 - 3y
x = -10.5 - 3/2y

-10x + 2y = 20
-10(-10.5 - 3/2y) + 2y = 20
105 + 15y + 2y = 20
105 + 17y = 20
17y = -85
y = -5

2x + 3y = -21
2x + 3(-5) = -21
2x - 15 = -21
2x = -6
x = -3

Therefore, the coordinates are (-3, -5).

Variable y varies directly with x2, and y = 196 when x = 7.

Alenkinab [10]

$y=kx^2$
k - a constant

$y=196 \ when \ x=7 \\
196=k \times 7^2 \\
196=49k \\
\frac{196}{49}=k \\
k=4 \\ \\
\boxed{y=4x^2}$
