Use the distance formula and the pythagorean theorem to find the distance, to the nearest tenth, from t (4,-2) to (-2,3).

distance =  which is 7.8 to the nearest tenth

Explanation:
The distance between two points can be calculated using the following formula:
distance = 

In the given, we have:
point (4,-2) representing (x1,y1)
point (-2,3) representing (x2,y2)

Substitute with the givens in the above formula to get the distance as follows:
distance =  which is 7.8 to the nearest tenth

Hope this helps :)
