Graph 1 and graph 4 represents the graph of linear equations.
Here, graph 1 and graph 4 shows straight line and graph 2 & 4 shows curve.
What is the graph of linear equation?
Linear function are those whose graph is a straight line.
Explanation for the correct options:
In graph 1 and graph 4 we can see that it has equal slope at every point and shows straight line.
Similarly at every point the slope remains constant.
Hence these two are graph of linear equation.
Explanation for incorrect options:
In graph 2 and graph two slopes are not constant at each points .
Thus , these are not representing the graph of linear equations.
