The intersection of two lines is a point which is a solution to the two equations.
x + y = 3 2x – y = 3 (2, 1) That means that we can use the coordinates of the point of intersection as x and y values for both equations 2 + 1 = 3 3 = 3 2(2) – 1 = 3 3 = 3 www.upcatreview.com
To obtain the intersection of the two lines, we can use any of the following methods:
Graphing
Substitution
Elimination
The crudest of all the methods… thus it’s not advisable to use this one. The easiest to remember We’ll use this one to solve the problem www.upcatreview.com
In elimination, as the name implies, we eliminate one of the variables.
x – y = 1 2x – y = 5 result: an equation with only one variable We can try to eliminate y for this problem Elimination is done by adding or subtracting the two equations www.upcatreview.com
