Answer:
the last option
Step-by-step explanation:
test with point (1,6):
x=1 and y=6
4x + 5y - 34 = 0
4(1) + 5(6) - 34 = 0
0 = 0
test with point (6,2)
x=6 and y=2
4x + 5y - 34 = 0
4(6) + 5(2) - 34 = 0
0 = 0
For a) the pattern rule goes 12+(12x2)=36 36+(12x4)=84
So the pattern rule is double the number and then times it by twelve to get to the next answer
y = k/x, where k is the variation constant.
We need to find k.
5 = k/15...This equation leads to the correct value of k (our variation constant).
5(15) = (k/15)(15)
75 = k
Done!
