If you're referring to the line:
y = x - 2
Then it has a slope of zero.
On the other hand, if you're referring to the curve:
y = x-2
Then at any x position, it has a slope of -2/x3.

It shows the relationship of y in terms of x. [y = (yIntercept) + ((slope)*(x))] [slope = (y2 - y1)/(x2 - x1)]
It is y1-y2=m(x1-x2). m is the slope of the line. The point should be where the 2nd y2 and x2 are. Ex: slope = 5 (3,-4) The answer to this would be: y+4=5(x-3)
the formula used to calculate a slope is: m=y2-y1/x2-x1
No because the slope is: (y1-y2)/(x1-x2)
Points for example: (4, 8) and (2, 4) Slope: (8-4)/(4-2) = 2 The slope formula is m = (y2 - y1) / (x2 - x1) where the 2 points are (x1,y1) and (x2,y2)
