Math Problem Statement

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

Solution

To determine the distance between the two points on the graph, we will use the distance formula, which is:

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


Step 1: Identify the coordinates of the two points.

From the graph:

  • The first point P1P_1 has coordinates (5,3)(-5, -3),
  • The second point P2P_2 has coordinates (2,1)(2, 1).

Step 2: Apply the distance formula.

Substitute (x1,y1)=(5,3)(x_1, y_1) = (-5, -3) and (x2,y2)=(2,1)(x_2, y_2) = (2, 1) into the formula:

d=(2(5))2+(1(3))2d = \sqrt{(2 - (-5))^2 + (1 - (-3))^2}

Simplify the differences:

d=(2+5)2+(1+3)2d = \sqrt{(2 + 5)^2 + (1 + 3)^2}

d=72+42d = \sqrt{7^2 + 4^2}

Square the values:

d=49+16d = \sqrt{49 + 16}

d=65d = \sqrt{65}


Step 3: Simplify the radical.

The square root of 6565 cannot be simplified further because 6565 factors as 5×135 \times 13, both of which are primes.

Thus, the distance between the two points is:

65\sqrt{65}


Step 4: Match with the answer choices.

None of the given options include 65\sqrt{65} directly. It's possible that either the choices or the points may have been misinterpreted. Could you confirm if you'd like me to revisit this graph or recheck the question? Let me know!
