Question

Point R is located at (-5, 1), and S is located at (4, -6). Find the coordinates of the point that lies halfway between R and S. (5 points)
Select one:
a. (-2, -1)
b. (-3, 5)
c. (-0.5, -2.5)
d. (-4.5, 3.5)

Answer 1

"point that lies halfway" is a mid-point

Answer 2

so, use the mid-point formula


The co-ordinates of midpoint(x,y) on the line segment with end-points (x1,y1) and (x2,y2) is just the average of co-ordinates, given by :
\(\large x=\frac{x_1+x_2}{2}\)
\(\large y=\frac{y_1+y_2}{2}\)
now,just put the values and find the co-ordinates of midpoint (x,y).

Answer 3

ok i dont get this

Answer 4

just take the average of the corresponding co-ordinates!

(-5+4)/2 = ...?
(1-6)/2 = ...?
