(d): y = mx+n
m = -2/3 ⇒ y = (-2/3)x +n
A(-4, 6) ∈ d ⇒ 6 = (-2/3)·(-4) +n ⇒ 6 = 8/3 +n ⇒
⇒ n = 6 - 8/3 ⇒ n = 10/3
Now, we have:
y = (-2/3)x +10/3
C bruh I gotta add a few more characters so bla bla bla bla mathy things banana pancake
15-7 is 8! so 8 is the length of the side with the ?
4 times 7 gets 28 and 7-4 gets you 3
The most reasonable would be grams.
