Question 157963


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



{{{m=(-5--5)/(2--1)}}} Plug in {{{y[2]=-5}}}, {{{y[1]=-5}}}, {{{x[2]=2}}}, and {{{x[1]=-1}}}



{{{m=(0)/(2--1)}}} Subtract {{{-5}}} from {{{-5}}} to get {{{0}}}



{{{m=(0)/(3)}}} Subtract {{{-1}}} from {{{2}}} to get {{{3}}}



{{{m=0}}} Reduce



So the slope of the line that goes through the points *[Tex \LARGE \left(-1,-5\right)] and *[Tex \LARGE \left(2,-5\right)] is {{{m=0}}}
