If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
-y + y equals 0.
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
For y - 2y - 3y equals 0, y equals 0.
y - 3 = 0 y = 3
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
-y + y equals 0.
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
For y - 2y - 3y equals 0, y equals 0.
b = y - mx.
y= -2x
y - 3 = 0 y = 3
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
y=x+4
y = -6
-3
y=5-x
