Question 995435

 ({{{x[1]}}},{{{x[2]}}})=({{{x}}},{{{17}}})
and

({{{x[2]}}},{{{y[2]}}})=({{{-20}}},{{{-4}}})


slope:{{{m=7/6}}}


use formula for slope:


{{{m=(y[2]-y[1])/(x[2]-x[1])}}}

{{{7/6=(-4-17)/(-20-x)}}}

{{{7/6=(-21)/(-20-x)}}}

{{{7/6=-21/(-20-x)}}}........cross multiply


{{{7(-20-x)=-21*6}}}

{{{-140-7x=-126}}}

{{{-140+126=7x}}}

{{{-14=7x}}}

{{{x=-14/7}}}

{{{x=-2}}}

so, your point is ({{{-2}}},{{{17}}})
