Independent Dependent Line Graph

What is something on a graph that you have control over and isn't changed by any other variable?

• Independent variable

• Dependent variable

• Controlled variable

• Extraneous variable

Time such as minutes, days, and months will always be a(n) ________________ variable when graphing.

• Controlled

• Independent

• Dependent

• Extraneous

What type of variable is the "Price per Bushel (dollars)" in this graph?

• Bar graph

• Dependent variable

• Independent variable

• Controlled variable

Select the correct independent and dependent parts of the graph .

(choose 2 answers)

• The independent variable is distance

• The independent variable is time

• The dependent variable is distance

• The dependent variable is time

Where do you graph the Independent Variable?

• X axis

• Y axis

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.
