Math Variables on Graphs and Tables

A linear function creates a ​ (a)   when represented on a graph.​

• straight line

• scatter plot

• bar graph

This graph shows a line and it's slope. What does the slope represent?

• How steep the line is.

• What the outlier is.

• What association of the line

• The distance.

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.
