Question

What is the slope-intercept form of the function that contains the points (6,2) and (4,8)?

Answer 1

not really, that why i put it up!

Answer 2

?

Answer 3

2 - 8 = 6 6 - 4 = 2

Answer 4

oh ok

Answer 5

m = -3 b = 2

Answer 6

i think?

Answer 7

ok that's what i put in right

Answer 8

final answer

Answer 9

\[\frac{2-8}{6-4}\]
\[\frac{-6}{2}\]
m = -3

y = mx + b
(now choose any of the points, either (6,2) or (4,8)

Using (6,2) : x=6 y=2
(2) = (-3)(6) + b
2 = -18 + b (we now move 18 to the other side and change it from negative to positive)
2 +18 = b
20 = b (b = y-intercept)

Using (4,8): x=4 y=8
(8) = (-3)(4) + b
8 = -12 + b
8 + 12 = b
20 = b

*using either point will get you the same answer.
