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 the two points \((-2, -1)\) and \((2, 4)\), we can use the Pythagorean Theorem. The distance \(d\) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by the formula:

\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]

Substituting the values from our points:

  • \(x_1 = -2\), \(y_1 = -1\)
  • \(x_2 = 2\), \(y_2 = 4\)

Now, calculate the differences:

\[ x_2 - x_1 = 2 - (-2) = 2 + 2 = 4 \] \[ y_2 - y_1 = 4 - (-1) = 4 + 1 = 5 \]

Now substitute these differences back into the distance formula:

\[ d = \sqrt{(4)^2 + (5)^2} \] \[ d = \sqrt{16 + 25} \] \[ d = \sqrt{41} \]

Now, we need to round to the nearest hundredth:

\(\sqrt{41} \approx 6.4\) (using a calculator or estimating).

So, rounding to the nearest hundredth, the distance is approximately:

6.40.

From the options provided, the correct response is 6:40.
