Question 206462
Note: *[Tex \LARGE \left(x_{1}, y_{1}\right)] is the first point *[Tex \LARGE \left(-4,-10\right)]. So this means that {{{x[1]=-4}}} and {{{y[1]=-10}}}.

Also, *[Tex \LARGE \left(x_{2}, y_{2}\right)] is the second point *[Tex \LARGE \left(-18,-11\right)].  So this means that {{{x[2]=-18}}} and {{{y[2]=-11}}}.



{{{m=(y[2]-y[1])/(x[2]-x[1])}}} Start with the slope formula.



{{{m=(-11--10)/(-18--4)}}} Plug in {{{y[2]=-11}}}, {{{y[1]=-10}}}, {{{x[2]=-18}}}, and {{{x[1]=-4}}}



{{{m=(-1)/(-18--4)}}} Subtract {{{-10}}} from {{{-11}}} to get {{{-1}}}



{{{m=(-1)/(-14)}}} Subtract {{{-4}}} from {{{-18}}} to get {{{-14}}}



{{{m=1/14}}} Reduce



So the slope of the line that goes through the points *[Tex \LARGE \left(-4,-10\right)] and *[Tex \LARGE \left(-18,-11\right)] is {{{m=1/14}}}
