The given graph contains a line

The general equation of the line is


y=mx+b

By observing the graph, we get two points which lie on the line

that are (0,3) and (-4,0)

Substitute x=0 and y=3 in the equation of the line, we get


3=m(0)+b


b=3

Substitute x=-4 and y=0 in the equation of the line, we get


0=m(-4)+b


4m=b

Substitute b=3, we get


4m=3

Transferring 4 to the right-hand side, we get


m=(3)/(4)

By substituting b=3 and m=3/4 in the equation of the line, we get


y=(3)/(4)x+3

We get the equation of the given line.

By giving many values to x, we will get many values for y.

Hence this graph has infinite solutions.
