3x+2y=8 is this function a quadratic?

Step-by-step explanation:

Let's select values for X, and find the corresponding Y values:

X = -3, Y = 8.5

X = -2, Y = 7

X = -1, Y = 5.5

X = 0, Y = 4

X = 1, Y = 2.5

X = 2, Y = 1

X = 3, Y = -0.5

So our coordinates are:

(-3, 8.5) ; (-2, 7) ; (-1, 5.5) ; (0, 4) ; (1, 2.5) ; (2, 1) and (3, 0.5)

Graph these on a chart to visualize:

(In picture)

We can see that this is a decreasing linear function, not quadratic. Quadratic functions create a symmetrical curve, which this is not.
