Use the image to answer the question.

A graph shows four quadrants with the x-axis and y-axis both ranging from negative 5 to positive 5 in increments of 1. Unlabeled data points marked are at left parenthesis negative 2 comma negative 1 right parenthesis, and at left parenthesis 2 comma 4 right parenthesis. A straight line joins the two lines with a positive slope.

Apply the Pythagorean Theorem to find the length between the two points. Round your answer to the nearest hundredth, if necessary.

To find the distance between two points on a graph, we can use the Pythagorean theorem.

The two points given are (-2, -1) and (2, 4).

To find the length between these two points, we need to find the horizontal and vertical distances between them.

The horizontal distance is the difference in x-coordinates: 2 - (-2) = 4.

The vertical distance is the difference in y-coordinates: 4 - (-1) = 5.

Using the Pythagorean theorem, we can find the length between the two points:

length = sqrt((horizontal distance)^2 + (vertical distance)^2)
= sqrt(4^2 + 5^2)
= sqrt(16 + 25)
= sqrt(41)

Rounded to the nearest hundredth, the length between the two points is approximately 6.40.
