Question

What mathematical relationship between variables is suggested by a graph showing a diagonal line from the lower left to the upper right of the graph? A. Inverse B. Linear C. Quadratic (power)

Answer 1

Answer:

The mathematical relationship between variables is :

                         B. Linear

Step-by-step explanation:

The graph is:

A diagonal line which starts from the lower left and it goes to the upper right.

Since, the curve is a line.

This means that the relationship between the two variable is a linear relationship.

Also, the graph is a increasing graph since with the increase in the values of one variable the value of the other variable also increases.

Hence, the correct answer is: Option: B  Linear

Answer 2

you can see the distance between the intervals in the graph more easily because you can see how far the plots are away from each other by connecting the w/ lines. Ex you had 5 on a graph and you had 12 after it there is an interval of 8 in between so you can visually see how far apart the numbers area simple 2d xy line graph has only the possibility for 2 different variables (x and y).. for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs. Hope this helps.
