How would bivariate data best be displayed?

on a scatter plot with a linear relationship between price and time

on a scatter plot with an exponential relationship using time, price, and interest earned

on a graph of a linear function using time, price, and interest earned

on a graph of an exponential function using volume, interest, and dollar value

on a scatter plot with a linear relationship between price and time

Step-by-step explanation:

Bivariate indicates there are two variables plotted on a graph for seeing a relationship among plotted points. The scatter plot serves this purpose when plotting price and time. The other answer choices use more than two variables.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
