By using the equation of a straight line y = mx+b whereas m is the slope of the line and b is the y intercept
A line whose slope is not constant or not defined. A curved line, a discontinuous line, a vertical line are some examples.
By using the straight line equation of y = mx+c whereas m is the slope and c is the y intercept

No. A linear graph has the same slope anywhere.
In a linear graph the slope is the same everywhere, assuming vertical line graphs are not allowed. Depending on context, a vertical line (say x = 3) is not always allowed. If the graph is a vertical line then the slope is infinite at the single value of x. (That would be 3 in the example above.) The slope would then be undefined elsewhere.

formula
A protractor.

take two ordered pairs. then do difference of y's divided by difference of x's and that is your slope
1
If the slope of a line is m then the slope of an altitude to that line is -1/m.
