To find: the advantage and disadvantage of solving the system of linear equations by graphing.
Answer to Problem 13CT
Advantage is it can visually determine the solution and requires very little algebra and disadvantage is point of intersection may not be accurate as some may have decimal solutions.
Explanation of Solution
Given:
Linear equation.
Concept used:
Linear transformational graphing translation:
For instance, if the lines cross at a shallow angle it can be just about impossible to tell where the lines crossed.
Calculation:
Advantage of solving system of linear equations by graphing are:
It can visually determine the solution and requires very little algebra.
Disadvantages of solving system of linear equations by graphing are:
The point of intersection may not be accurate as some may have decimal solutions.
Some linear equations can be difficult to graph because of the slopes.
Hence, advantage is it can visually determine the solution and requires very little algebra and disadvantage is point of intersection may not be accurate as some may have decimal solutions.
