y = 8 - 2*x

5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8

If you plug in y for the x function, and it equals the answer you got, it is right.

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

A function

Yes.

y = -8 is a function because when graphed, it passes the vertical line test.

Y = 2X + 8 is a linear function of the form, Y = mX + c. A line.

Yes, 2y = 8 is a linear function. 2y = 8 is the same as y=8/2, or y=4, which is a vertical line.

No.

y = 2, 4, 6, 8

y = 8 - 2*x

5x - 8 = yWhen y = 1,5x - 8 = 1Add 8 to each side of the equation:5x = 9Divide each side by 5:x = 9/5 = 1.8

16. Because if y=8 then the question becomes 8+8. Which equals 16.

yees because if you divide everything by 8 to get y=7/8+3x/8 which is a linear function since it fits the equation y=mx+b

Transitive property: If 8 equals x and x equals y, then 8 equals y.

y = x This is a line and a function. Function values are y values.
