That makes no sense, there is no y in the equation so y cannot equal anything.
4
-2
No, y=x-2 is linear.
X - Y = 2 When X = 3 you have 3 - Y = 2 Moving Y to RHS: 3 = Y + 2 Moving 2 to LHS: 1 = Y
The equation is y=x(x+1)(x-2)2
x = 2 and y = -4
4
-2
Half correct because x = 2 and y = 6
y=x-2
No, y=x-2 is linear.
x = 9/2 or x = -2 Solved by using the quadratic equation formula.
y = -5
X - Y = 2 When X = 3 you have 3 - Y = 2 Moving Y to RHS: 3 = Y + 2 Moving 2 to LHS: 1 = Y
The equation is y=x(x+1)(x-2)2
If: x+2 = y+6 Then: y = x-4
