Question

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

y=___x + ___

Answer 1

first, find the slope

Answer 2

....sorry brain fart. lol how do i do that again?

Answer 3

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

Answer 4

Well first find the slope, using the following formula: \[m = \frac{ y_{2}-y _{1} }{ x _{2}-x _{1} }\] where your coordinates represent \[(x_1,y_1)~~\text{and}~~(x_2,y_2)\]
Once you manage to get that, plug in m and your first coordinates in the point - slope form: \[y-y _{1}=m(x-x _{1})\] do some little algebra and eventually you will have slope - intercept form \[y=mx+b\]

Answer 5

(8-2)/(4-6)

Answer 6

slope is -3

Answer 7

i got that too

Answer 8

now use one of the points and the slope.
y-y=m(x-x)

Answer 9

(6, 2) and slope =-3
y-2=-3(x-6)

Answer 10

solve for y

Answer 11

y-2=-3x+18

Answer 12

-3x+ 20

Answer 13

yes
y=-3x+20

Answer 14

yay
