If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656

algebraic

Slope for the equation y equals 7 is zero.

x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656

Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".

y - |x| is an expression, not a function.

Slope for the equation y equals 7 is zero.

No. [ y = 4x2 ] is a quadratic equation.

x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656

x = 0 and y = 4

x = 2 and y = -4

The equation is y + 2 = 12.
