Question

write an equation in slope-intercept form of a line containing the points( 1/2,6) and (-1/2,8)
a)y=-2x+7
b) y=-x+5
c)y=-x+7
d)y=-2x+5

Answer 1

a

Answer 2

slope=(y2-y1)/(x2-x1)=-1

Answer 3

How??

Answer 4

-1/2-1/2=-2/2=-1

Answer 5

y-6=-2(x-1/2)
y=-2x+1+6=-2x+7

Answer 6

i think iy is c

Answer 7

m=6-8/(1/2+1/2)=-2

Answer 8

huh?
isn't m=(y2-y1)/(x2-x1)

Answer 9

yes

Answer 10

then??? How did u get -2?

Answer 11

what did u get?

Answer 12

-1

Answer 13

(1/2,6), (-1/2,8) are the points

Answer 14

6-8/(1/2+1/2)=-2.....no?

Answer 15

yea so 8-6=2
and -1/2-1/2=-1
and ur right

Answer 16

OOPS!!!

Answer 17
