FIND THE SLOPE OF THE LINE CONTAINING THE GIVEN PAIR OF POINTS a(-2,3) and b(-4,6)??
solution
==>
(Ya - Yb)=slope(Xa - Xb)
slope = (Ya - Yb)/(Xa - Xb)
slope = ( 3 - 6 )/(-2 - [-4])
slope = (-3) / ( 2 )
==> slope = -3/2

equilateral triangle means that all the sides are the same (congruent). so your formula would be 22+22+22=P

if you know the side length, for squares, it is half the side length.

if you have a hexagon, the radius is equal to the side length. then you can use the Pythagorean theorem ( a squared + b squared = c squared). Hope that helped!

4q + 5 = 5
4q + 5 - 5 = 5 - 5
4q = 5
(4q)/4 = 5/4
q = 5/4 = 1.25

heather:
x's numbers are -2,1,4,6,11
y's numbers are 1,7,13,17,27

y(x) = 2*x+5

(to find this equation, draw the coordinates on paper (x, y); (-2, 1); (1, 7)...)

test:
y(-2) = 2*-2+5=1
y(1)= 2*1+5=7
y(4)=2*4+5=13
y(6)=2*6+5=17
y(11)=2*11+5=27
