In a recent Math Duel, my team began by graphing 51x+24+75. If our opponents graphed a line parallel to ours, they might have graphed

Question

A. 17x+16y=25
B. 17x+8y=50
C. 34x+8y+50
D. 34x+16y=50

Answer 1

Assuming you meant
51x+24y = 75,
you can divide by 3 to get
17x+8y = 25

So, 17x+8y = C
will be parallel, regardless of the value of C. (except C=25)

So, pick (B) because (D) is the same line as the original (obtained by multiplying through by 2/3).
