If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
Yes, y = 3+x is linear.
This is non-linear
Yes, y = -4x + 3 is a linear equation.
y = 2x + 1 IS a linear equation!

Yes
Linear.
Yes, y = -4x + 3 is a linear equation.
y = 2x + 1 IS a linear equation!
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
y = 0" the answer is YES.
-1
-5
Yes, y=-2+x is a linear function.
