-2
2 to the power of 4 is an expression, it is not an equation.
I assume you mean "u" as a variable. So, the equation is as follows : u+2=4 The goal here is to make the equation say u= To do that you simply subtract two from both sides of the equation: u+2=4 -2 -2 u=2 And there is your answer, u=2

(9+3) - (2 +4) = 6
6y-4 called in an equation = 2
4-2=2
24 x 12 = 288
4.
Coordinate: (1, 2) Slope: 4 Equation: y = 4x-2
4 x 2 = 8
If you mean points of: (2, -8) and (0, 0) then the slope is -4 and equation is y = -4x
Points: (4, -4) and (-2, 0) Slope: -2/3 Equation: y = -2/3x-4/3 or as 3y = -2x-4
