<u>How to Find the Distance Between Two Points</u>
Distance formula: d(P, Q) =√(x2 − x1)^2+(y2 − y1)^2
If you use this equation the answer will be 5.
The midpoint of (x1,y1) and (x2,y2) is

just average them
(4,1) and (-2,4)
the midpoint is

(1,-1.5)
Answer:
slope = 5/8
Step-by-step explanation:
use the slope formula to find the slope: 

The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
