Question

identify a slope for this line given points are:
(0,-2) (3,-5) (6,-8), (9,-11)

Answer 1

use all of this point to find slope
(0,-2) (3,-5) (6,-8), (9,-11)
the formula for slope
m=(y2-y1)/(x2-x1)

for ex using the first 2 points
(0,-2) =(x2,y2),,(3,-5)=(x1,y1)
m=(-2+5)/(0-3)=__?

and for
(3,-5), (6,-8)
m=(-8+5)/(6-3)=___?

and for
(6,-8), (9,-11)
m=(-8+11)/(6-9)=__? or
m=(-11+8)/(9-6)=__?

Answer 2

so the slope decrease by -12 as we change the points, is that right?

Answer 3

hmm if thats the case yes, but i havent compute them yet i just show you haw to do the solution on finding the slope.... :D

Answer 4

sorry, I was looking at the other problem

Answer 5

So should I list all of the slopes between the points?

Answer 6

Ok, I got it, Thanks for your help!

Answer 7

i think you should graph them and find out whats the picture of it, i think its all equal slope

Answer 8

ok good luck now, have fun :D

Answer 9

So the slope is -1

Answer 10

yes you got it.. :D
