What is an equation of the line that passes through the points (1, 4) and (-2,-8)? Put your answer in fully reduced form.

Need help

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

96 39 cause 135 -96=39 im smart (i used a calculater)

so mark-up is 0.4 multiplied by 180 = 72

answer: graphs are something you write or draw and equations are math problems
