M= y2-y1?x2-x1
m=4-(-1)/(-7)-8
m=5/-15
m=-3
The slope is -3
C=yt+y. Divide both sides by y and u get c/y=t+1 subtract 1. The ANSWER IS c/y-1=t
If a:b=c:d then a/b=c/d and ad=bc
so
if 16:14=64:60 then 16/14=64/60 and (16)(60)=(14)(64)
(16)(60)=960
(14)(64)=896
960≠896
not equivilent
the easiest way is to simplify them
16/14=8/7
64/60=32/30=16/15
not equal
not equivilent
