Suppose lines ef and gh are reflected over the line y = x to form the lines jk and lm. which statement would be true about the lines?

a.
line jk and line lm will be parallel.

b.
line jk and line lm will be perpendicular.

c.
the slope of line jk will be the same as the slope of line ef.

d.
the slope of line lm will be the negative reciprocal of the slope of line gh.

consider the line
y
=
x
y=x
.
if the line is dilated by a factor of 2, what is the equation of the resulting line?
if the resulting line is translated 3 units up, what is the equation of the resulting line?
