As Anand Mehta said, you could use partial derivatives. Or differentials, which is quite similar. It works like this: assuming that you have a surface area, "z", defined in terms of "x" and "y". At some specific point, the slope might be, for example:z = 0.5 delta x + 0.3 delta y
This means that for any increment (delta) in x, by a certain amount, z would increase by 0.5 times that amount; similarly, for any delta y (increment in y), z would increase by 0.3 times that amount.

There is no simple way: you could represent the slope in terms of partial derivatives.
y=mx+b is slope-intercept form y - y1 = m(x - x1) is point-slope form Used in algebra based math. On a graph; m is the slope b is the y-intercept x and y represent points
A single value for x and a single value for y represent a point, not a line. A point cannot have a slope.
If you mean: x-2y = 2 then it is y = 0.5x-1
y=x y=1x The slope is one.
No it is not an undefined slope; the slope of y = -x is -1.The standard form of a linear equation is y = mx + b, where m is the slope, and b is the y-intercept. In y = -x, the y-intercept is 0, and the slope is -1.
