Question 206055
Very  good  so  far.

Now,,  we  make  a  T  box,,and  just  plot  some  "arbitrary"  points
.
x,,,,,,,,,,,,y
.
0,,,,,,,,,,,,300,,,,,,,,,,y= 375 / 1.25 = 300,,,assume  x=0,,calc  y
.
250,,,,,,,,,,,0,,,,,,,,,,,x=375/1.5=250,,,assume y=0,,,calc  x
.
125,,,,,,,,,,150,,,,,,,,,,1.5(125) +1.25y = 375,,y=(375-187.5)/1.25 =150
.
just  plot  the  coordinates  on  the  x-y  grid,  and  connect  the  dots.
.
have  a  good  day
