Question 169747
slope is given by {{{m = (y[2] - y[1])/(x[2] - x[1])}}}

You are given two points, each in the form (x, y)

Pick up the two y coordinates and plug them into the slope equation. It doesn't matter with point you call 1 and which you call point 2. Just make sure to use both the x and y from the same point.

Let's call (-4, -2) as point 2 and (-6,-8) as point 1.
Then {{{x[1] = -6}}}, {{{y[1]=-8}}} and {{{x[2] = -4}}}, {{{y[2]=-2}}}

{{{m = ((-2) - (-8))/((-4) - (-6))}}}
{{{m = (6/(2))}}}
{{{m = 3}}}
