Question

Find the distance between the points (7,-6) and (-5,3). Write your answers as a whole number or a fully simplified radical expression. Do not round.

Answer 1

Answer:

15

Step-by-step explanation:

Let index 1 refer to the first point, while index 2 refers to the second one.

The distance d:

d²=(x2-x1)²+(y2-y1)²=(-5-7)³+(3-(-6))²=

(-12)²+9²=144+81=225=15²

d=15
