Bring y to one side and the rest to the other switching the positives to negative then you’ll get Y=114
Y=mx+b
so is 2

1 lesson $30
2 lessons $60
3 lessons $90
4 lessons $120
5 lessons $150
So from this set of numbers , it is apparent that the grqph in letter c represents the total costs for x numbers of lessonsseethati
