Question 674930
slope is {{{(y1-y2)/(x1-x2) = ((1/4)-(3/2))/(3-(1/2))}}}
...
{{{1/4 - 3/2 = 1/4 - (3/2)(2/2) = 1/4 - 6/4 = -5/4}}}
...
{{{3 - 1/2 = 3(2/2) - 1/2 = 6/2 - 1/2 = 5/2}}}
...
{{{(-5/4) / (5/2)}}}
knowing dividing is the same as multiplying the inverse
{{{(-5/4)(2/5) = -2/4 = -1/2}}}
...
slope is {{{highlight_green(-1/2)}}}
