Given the ordered pairs find the value of r that makes the slope equal to the given value (3 , r) and (7 , 2) m= 1/4 Possibles answers
A) r= -1
B) r= 2
C) r=1
D) r =3
E) r=0

C

Step-by-step explanation:

Calculate the slope m using the slope formula, then equate to

m =

with (x₁, y₁ ) = (3, r) and (x₂, y₂ ) = (7, 2)

m = = , then

= ( since denominators are both 4, equate the numerators )

2 - r = 1 ( subtract 2 from both sides )

- r = - 1 ( multiply both sides by - 1 )

r = 1 → C

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
