    Hmm - if you are given two points \(\rm (x_1 , y_1), (x_2, y_2)\) then the slope is\[\rm Slope = {y_2 - y_1 \over x_2 - x_1}\]

    No, @lucwex that's the slope-intercept form of the equation of an oblique line. Tho formula for slope is what @ParthKohli said.

    Right, Are they the same? No, So you have two different slopes.
