The monthly cost (in dollars) of water use is a linear function of the amount of water used (in cubic meters, m3). The cost for using 32 m3 of water is $43.31, and the cost for using 45 m3 is $60.86. What is the cost of using 44 m3 of water?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
