Independent and Dependent Variables with Graphs

What is wrong with this graph?

• The dependent variable is not labeled.

• The data that is graphed is incorrect and a different graph should have been used.

• The intervals on the x and y axis are written incorrectly.

• The color of the graph is not appropriate or professional

The independent quantities are graphed along the ________ -axis

• X- Axis

• Y - Axis

• None of the above

Choose the correct equation for the given graph.

• y = x + 2

• y = 4 + x

• y = x - 2

• y = 4 - x

Answer explanation

As we can see in the graph that the line is intersecting x axis at 2 and y axis at -2. So here we have got two points (2, 0) and (0, -2). Now let's substitute these points in y = x - 2 (2, 0) In LHS, y = 0 In RHS, x - 2 = 2 - 2 = 0 So, LHS = RHS (0, -2) In LHS, y = -2 In RHS, x - 2 = 0 -2 = -2 So, LHS = RHS Therefore, The graph in the figure is of the equation y = x - 2 and option 3 is the correct answer.
