To graph : the line in the system and check whether the system is consistent or inconsistent.

Explanation of Solution
Given information :
{3x+5y=−24x−y=5
Graph: Sketch the graph using graphing utility.
Step 1: Press WINDOW button to access the Window editor.
Step 2: Press Y= button.
Step 3: Enter the expression Y1=3x+5y=−2 and Y2=4x−y=5 which is required to graph.
Step 4: Press GRAPH button to graph the function.
The graph is obtained as:
The system is consistent because the line of the given equation intersect each other and the point of intersection of both line is x=1 and y=−1 .
To check the solution solved both the equation algebraically is obtained as:
Let, 3x+5y=−2 is the equation (i) and 4x−y=5 is the equation (ii).
3x+5y=−220x−5y=25_ [multiply 5 in equation (ii) ] 23x =23 [add equation]x=2323x=1
From this equation, substitute the value of x=1 into equation (ii).
4x−y=54⋅1−y=5 [substitute ]−y=5−4 y=−1
Hence, the solution of linear equation is x=1 and y=−1 .
Interpretation : From the above graph, it can be observed thatthe system is consistent because the line of given equation intersect each other and the solution of the system is x=1 and y=1
