Question

jane says that she can use addition to show that the graph of 2x-3y=1 and 2x+3y=2 are intersecting lines.In two or more complete sentences, describe the process of using addition to show that the lines are intersecting

Answer 1

Explanation:

Two lines in a plane can intersect, overlap, or be parallel. When two lines intersect they have a common point which lies on both lines. when graphed represent straight lines. Adding the two equations uses the Elimination method to solve for x and y. The x and y value obtained is the common point lying on both lines.

Answer 2

2x-3y=1
+2x+3y=2

4x=3 substitute 3/4 for x in the first equation..you get y=2/9.
x=3/4
