lets say you have to write 5x+6y=-12 in function form. when you are writing an equation in function form, you usually solve for f(x) or g(x), but in this case, y is the same as f(x) or g(x). so to write 5x+6y=-12 in function form, you do this: 5x+6y=-12 6y= -5x -12 subtract 5x from both sides y= -5/6x -2 divide both sides by 6

y = 0.5x - 0.3

5x + 5y = 19x = 3.8 - yory = 3.8 - x

y = 0.5x - 0.3
Y = 5X - 3It form a linear function; a line.

No. x2+5x is a polynomial, an algebraic expression or a formula, but it is not a function. It could be used to help define a function. {(x,y) | y = x2 + 5x , x any real number} is a function
5x²=0 X=0 the function y=5x² only intercepts x when x = 0

It is -5*(3x + 1), no exponents are required.
