The perpendicular bisector of the like segment connecting the points (-3, 8) and (-5, 4) has an equation of the form y = mx + b. Find m + b.

so, converting firstly the mixed fractions to improper fractions and then "adding".

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

nope.   happens to me as well.
