Question
Calculate the distance between the following points:
F(-9, -14) and G(1, -19)
Write your answer in simplest radical form.
Solution
To calculate the distance between two points in a plane, we can use the distance formula derived from the Pythagorean theorem, which is:
d = sqrt[(x2 - x1)² + (y2 - y1)²]
Here, F(-9, -14) is (x1, y1) and G(1, -19) is (x2, y2).
So, substituting the given values into the formula, we get:
d = sqrt[(1 - (-9))² + ((-19) - (-14))²] d = sqrt[(1 + 9)² + ((-19) + 14)²] d = sqrt[(10)² + (-5)²] d = sqrt[100 + 25] d = sqrt[125]
The simplest radical form of 125 is 5√5 (since 125 = 25*5 and square root of 25 is 5).
So, the distance between points F and G is 5√5 units.
