One endpoint of a line segment is at (−4, −2). the line is bisected by placing the midpoint of the line segment at (3, 1). what are the coordinates of the other endpoint? (−4, −6) (−0.5, −0.5) (10, 4) (9, 5)

(10, 4)

Step-by-step explanation:

The horizontal distance from (-4, -2) to the midpoint (3, 1) is 7, and the vertical distance is 3.  To find the other end point of this line segment, add 7 to the x-coordinate of the midpoint:  3+7 = 10, and add 3 to the y-coordinate of the midpoint:  1 + 3 = 4.  The coordinates of the other end of this segment are thus (10, 4) (the fourth possible answer choice).

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
