You cant since you have no measurements
you realize you could easily go around the whole perimeter w/ a tape measurer then add the sides together
Y-intercept 168
x-intercept (-21)


We need the exact value of

to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives

Plug this into either equation and you get

(It's guaranteed that

in this case because that already corresponds to

.)
