Question
find the distance between the two points in simplest radical form.
(8, -4) and (3, 8)
Step1: Recall distance formula
The distance \( d \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \).
Step2: Identify coordinates
Let \((x_1, y_1) = (8, -4)\) and \((x_2, y_2) = (3, 8)\).
Step3: Substitute into formula
Calculate \( x_2 - x_1 = 3 - 8 = -5 \) and \( y_2 - y_1 = 8 - (-4) = 12 \).
Then \( d = \sqrt{(-5)^2 + 12^2} \).
Step4: Simplify the expression
\( (-5)^2 = 25 \) and \( 12^2 = 144 \), so \( d = \sqrt{25 + 144} = \sqrt{169} \)? Wait, no, 25 + 144 is 169? Wait, 25 + 144 = 169? Wait, 25 + 144 is 169? Wait, 25 + 144: 25 + 144 = 169?

Step1: Recall distance formula
The distance \( d \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is given by \( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \).
