Math Problem Statement

Find the distance between the two points in simplest radical form.

Solution

To find the distance between the two points on the coordinate plane shown in the image, we use the distance formula, which is:

d=(x2x1)2+(y2y1)2d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

Let's identify the coordinates of the two points from the graph:

  • The first point (near the origin) appears to be at (4,2)(-4, -2).
  • The second point (above the x-axis) appears to be at (2,3)(2, 3).

Now, substitute these coordinates into the distance formula:

d=(2(4))2+(3(2))2d = \sqrt{(2 - (-4))^2 + (3 - (-2))^2}

Simplify each term:

d=(2+4)2+(3+2)2d = \sqrt{(2 + 4)^2 + (3 + 2)^2}

d=62+52d = \sqrt{6^2 + 5^2}

d=36+25d = \sqrt{36 + 25}

d=61d = \sqrt{61}

Thus, the distance between the two points in simplest radical form is 61\sqrt{61}.
