The question asks for a function of 'y', so we'll show 'x' as a function of 'y':
Given: 8x - 9y = 2
Add 9y to each side:
8x = 2 + 9y
Divide each side by 8:
x = 2/8 + 9y/8
or
x = 1/8 (2 + 9y).
==================================================
If the questioner actually wants to see it in the more familiar form of [ y = a function of x ],
we can massage the original equation around to show that as well.
Given: 8x - 9y = 2
Subtract 8x from each side:
-9y = 2 - 8x
Multiply each side by -1:
9y = 8x - 2
Divide each side by 9:
y = 8x/9 - 2/9
or
y = 1/9 (8x - 2)
f(x)=2X-2

yes, 1/2 equals 0.5
It is 1.2164
y = 8 - 2*x
x + y = -2 y = -x - 2 f(x)= - x -2
g = f(x) = 3x + 2
Yes.
Yes, y=-2+x is a linear function.

Y=X^2 is a function for it forms a parabola on a graph.
f(x)=2X-2
You can write "equals". It would be perfectly fine to say "2 + 2 equals 4". It's jsut that, it's much more common to use "=", just because it's easier probably.

y = 2, 4, 6, 8
Generally, function values are Y values, so.......... 6X + 2Y = 24 subtract 6X from each side 2Y = - 6X + 24 divide both the integers on the right by 2 Y = - 3X + 12 -------------------------the function
