Which set of coordinates, paired with (-3, -2) and (-5, -2), result in a square?
dsp73

Answer:

  (c)  (-3, 0) and (-5, 0)

Step-by-step explanation:

The given coordinates are -3 -(-5) = 2 units apart on the horizontal line y=-2.

Then the needed coordinates will be on the vertical lines x=-5 and x=-3, and will have y-coordinates that are different from -2 by 2: either -4 or 0.

The points that meet these requirements are (-3, 0) and (-5, 0).

<h3>What is a circle graph?</h3>

A circle graph, also known as a pie chart, is a circular statistical visual that is divided into slices to demonstrate numerical proportion. In a pie chart, the arc length of each slice is proportional to the quantity shown. A pie chart is a graphical representation of data that takes the form of a circular chart or pie, with the slices representing the magnitude of the data. A list of numerical variables as well as category categories is required to represent data in the form of a pie chart.

A circle graph, also known as a pie chart, is a type of graph that is used to visually represent information and statistics. A circle graph is commonly used to demonstrate a study's proportionate outcomes. The arcs of a circle graph are proportional to the percentage of the population who responded to a specific question.

In this case, it can be used to show the students' grade points. Finally, D is the correct answer.
