If a line segment has endpoints a(3x + 5, 3y) and b(x − 1, −y), what are the coordinates of the midpoint of ab ?
(x + 3, 2y)
(2x + 3, y)
(2x + 2, y)
(4x + 4, 2y)

You need to use the midpoint formula of (x1+x2)/2,(y1+y2)/2

put in the actual points will look like this. (3x+5+x-1)/2,(3y-y)/2

now solve to get (4x+4)/2,(2y)/2

finish (2x+2,y)

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
