Use the distance formula to find the distance between the two points

9.) c(-9,-1) and d(7,3)

10.) e(5,-5) and f(1,-6)

11.) g(-5,3) and h(2,-8)

9.) -2/2 = -1

10.) -6/-11 or 6/11

11.) -3/-11 or 3/11

Step-by-step explanation:

this is easy XD

So, first step the midpoint formula: (x1 + x2 / 2, y1 + y2 /2 )

9.) c(-9,-1) and D(7,3)  > you should know the x and y and plug in :D

10.) E(5,-5) and F(1,-6) > you should know the x and y and plug in :D

11.) G(-5,3) and H(2,-8)> you should know the x and y and plug in :D

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!
