    The slope of any line is defined by the difference between the y-coordinates of the points divided the difference between the x-coordinates, so, the formula looks like this: \[m _{ab}=\frac{ y_2-y_1 }{x_2-x_1 }\] So, applying it for the points: \[m=\frac{ 4-(-4) }{ 3-(-1) }\] So, all you have to do is operate the fraction and see what you obtain as a result.

    Not really, first off you have to operate the multiplication of negatives on both the numerator and denominator: \[m=\frac{ 4-(-4) }{ 3-(-1) }\] \[m=\frac{ 4+4 }{ 3+1 }\]

    No, you have to sum 4+4 and divide it by 4.

    @Owlcoffee _____ is the difference in x-coordinates ?

    No, the difference between the x coordinates is "x2-x1" which is below the division line.
