How to solve fractions number lines

First you want to have a starting point which is most of the time 0. The. You need an end point for example 1. If you need to figure out if something is equivalent, you need to compare with two number lines and they have to be under one another. For an expression you need to cross out what you don’t need. For example, 7/10 - 3/10 you would cross out the 8/10, 9/10, and 1. Next, you would need to cross out three of the seven remaining fractions in order. 7/10, 6/10, 5/10 leaving you with the bigger number in the group that is remaining which is your answer. 4/10

B) since the graph does not have any y cordinates then there are no points of intersection of the graphs of the equations. basically they never intersect however they are parallel
