Use the image to answer the question.

A graph shows quadrant 1 with the x-axis and y-axis ranging from 0 to positive 9. Data points marked are at left parenthesis 3 comma 2 right parenthesis, and left parenthesis 7 comma 8 right parenthesis. A straight line joins the two points forming a positive slope.

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

(1 point)

Answer 1

To find the length between the two points, we can use the distance formula, which is derived from the Pythagorean Theorem.

The distance formula is: d = √((x2-x1)^2 + (y2-y1)^2)

Using the given points (3, 2) and (7, 8), we can substitute these values into the distance formula.

d = √((7-3)^2 + (8-2)^2)
= √(4^2 + 6^2)
= √(16 + 36)
= √52
≈ 7.21

Rounded to the nearest hundredth, the length between the two points is approximately 7.21.
