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. Data points marked are point A at left parenthesis 2 comma negative 3 right parenthesis, and point B at left parenthesis 5 comma 5 right parenthesis.

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

To find the length between the two points A(2, -3) and B(5, 5), we can use the distance formula, which is derived from the Pythagorean Theorem. The formula for the distance \(d\) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:

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

For the given points A(2, -3) and B(5, 5):

  • \(x_1 = 2\), \(y_1 = -3\)
  • \(x_2 = 5\), \(y_2 = 5\)

Now, plug in the coordinates:

\[ d = \sqrt{(5 - 2)^2 + (5 - (-3))^2} \] \[ d = \sqrt{(3)^2 + (5 + 3)^2} \] \[ d = \sqrt{3^2 + 8^2} \] \[ d = \sqrt{9 + 64} \] \[ d = \sqrt{73} \]

Now, we can calculate the numerical value of \(\sqrt{73}\):

\[ \sqrt{73} \approx 8.54 \]

So, the length between the two points, rounded to the nearest hundredth, is approximately \(8.54\).

The correct response is:

8.54
