Question

if points r=(6,4), q=(4,3), and p=(-2,b) are collinear whats the value of b??

Answer 1

compare the slope

Answer 2

collinear mean they will be part of the same line

Answer 3

slope using r q= slope using qp

Answer 4

\[(6,4),(4,3),(2,1),(0,0)\]

Answer 5

u mean rq=qp?

Answer 6

u have 2 points can find the slope ??

Answer 7

yes ok got that @gorv

Answer 8

ok :)

Answer 9

answer is -3? @gorv

Answer 10

(4-3)/(6-4)=(3-b)/(4-(-2))

Answer 11

now solve this

Answer 12

0 @gorv

Answer 13

oh my you can do that if you like, but i think the pattern is much easier to see

Answer 14

\[(6,4),(4,3)\] first coordinate goes down by 2, second goes down by 1

Answer 15

yeh i was doing but i didnt get the right answer thats why i post @satellite73
