Determine whether the lines are parallel, intersect, or coincide. y-7x=6, y+7x=8

The slope for the first problem given is -7

The slope for the second problem is 7

As these are the same slope and not opposite reciprocals, the lines are neither parallel or perpendicular.

This means that the lines will cross at a point at some point in the graph, meaning that your answer would be that the lines intersect.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
