How do you solve the system of equations by graphing and then classify the system as consistent or inconsistent #2x+y=0# and #5x-y=7#?
1 Answer
graph{(2x+y)(5x-y-7)=0 [-10, 10, -5, 5]}
Explanation:
Given that,
Replacing,
Replacing
The values are consistent.
Alternatively ,
Consider
and for
You would get two lines in the graph. Mark the point of intersection and that's the solution for the equations.
Here, the lines meet at (1,-2). Therefore the solution is,
P.S. to get the points to plot on the graph for both the equations, replace
