Question

If (2,4),(x,8) and the slope is -2 what is x

Answer 1

Answer:

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 = $\frac{Y2 - Y1}{X2 - X1}$

Or, -2 =   $\frac{8 - 4}{X  -2}$

Or, -2 = $\frac{4}{X - 2}$

Or, (-2)× (X - 2) = 4

Or, X - 2= -2

∴ X =-2 +2

so, X = 0       Answer
