Question

how to mx+b= y with two points (-2,0) (-2,-2)

Answer 1

first find the slope

Answer 2

and then pick any of the points u have!

Answer 3

like this : slope = -2-0/ -2+2 = -2/0 = undefined / u have an undefined slope!

Answer 4

so the answer is y=-2

Answer 5

To define a line you need 2 points or a direction.
To find the vector direction you just need to do for example (-2,0) - (-2,-2) = (0,2)
This is the line equation formula:

(x,y) = (-2,0) + k(0,2)

if you solve for x you'll get:
x = -2 + 0*k
y = 0 +2*k (=) k = y/2

substituting on the "x" equation:

x = -2 + 0 * (y/2)

x = -2

this is a line parallel to y-axis...

in y=mx + b format it will be: 0=1 * x +2

Answer 6

oh my answer is incorrect??

Answer 7

You prolly made a mistake somewhere. Don't worry, it happens even to the best of the best :)

Answer 8

lol! oh yeaaa!! thank youu!! :)
