Which set of points lies on the graph of x = -2?

inysia [295]

If you use Desmos it'll give you these points:
(-2,0)
(-2,2)
(-2,-2)
Since it's perfectly straight line, all the points with begin with -2. It's the same for graphs like y=-2, which would make them all end in -2. Hope this helped!

How did I lose 5 points?

PolarNik [594]

x + 4 = 3x - 8, is assuming D is the midpoint, and therefore ED = DB.

all we know is that D is <u>somewhere</u> in EB.

$\bf E\stackrel{x+4}{\rule[0.35em]{17em}{0.25pt}}D\stackrel{3x-8}{\rule[0.35em]{10em}{0.25pt}}B
\\\\\\
EB=ED+DB\implies EB=(x+4)+(3x-8)\implies EB=4x-4$
