Step-by-step explanation:</h3>
Note: The solution of a graph is the intersection of 2 lines.
<u>Plotting the solution on the graph:</u>
To plot the solution on the graph, 
- Look for the intersection point of the two lines. 
- Make a dot on the graph to represent the solution.
<u>Identifying a solution on the graph:</u>
To identify the solution, you willl need to determine it's coordinates. 
      1. Determine the x and y coordinate by drawing a line going                                 downwards and rightwards. Keep in mind that the                                               intersection of the lines on the x and y axis are the x and y                               coordinates repectively. 
- (It is suggested that the line should be drawn with a ruler). 
     2. The x and y coordinate obtained should be put in (x,y) form.
<u>Determining the solution on the graph:</u>
⇒ Intersection point: (x, y) = (x = -3; y = 1) = (-3, 1)                [Refer to image]
