Answer:
Step-by-step explanation:
He had the incorrect slope for the second line, his line has a positive slope of one while the equation has a slope of negative 1.
x+y=1
y=-x+1
He graphed x+1 instead of -x+1
If he graphed them correctly the lines would intersect when the equations were equal
2x+4=-x+1
3x+4=1
3x=-3
x=-1, making y=2x+4 become
y=2(-1)+4
y=2
So the solution was supposed to be the point (-1,2)
You question implies simple subtraction is needed:

If you use the real Pi , 3.140625 , from a real ratio 201 /64 , you would get 37.6875 inches . All ruler measurements like 1/2 , 1/4, 1/8 ,1/16 … is where the last decimal integer ends in 5 , just like the real Pi . If you use the present day Pi , your decimal integer circumference length keeps getting ever smaller , 10 , 100 , 1000 … in this case you would have a shrinking diameter . You are better off using the real Pi, that i have proven with Quora. Richard Eicholtz
