If (2,,8) and the slope is -2 what is x

X = 0

Step-by-step explanation:

Given points of line as (2 , 4) and (X , 8)

And slop of line ( M )= -2

Now X and Y co-ordinates can be written as

X1 = 2                X2= X

Y1 = 4                Y2 = 8

Now as we know

slop =

Or, -2 =  

Or, -2 =

Or, (-2)× (X - 2) = 4

Or, X - 2= -2

∴ X =-2 +2

so, X = 0       Answer

no, because the sides are not congruent
