D, its (x,y) and (8.2,5.7) are the only ones that match up
Check the picture below. So let's use those two points on the line.

bearing in mind that the standard form is also a general form.
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
S=4P+4Q
S=4(P+Q)
S/4=P+Q
S/4-P=Q
Q=S/4-P
