The endpoints of a line segment are located at (–3, –4) and (–15, –20). what are the coordinates of the midpoint of the line segment? a. (–10.5, –14) b. (–9, –12) c. (–7.5, –10) d. (–6, –8)

Answer B:  (-9, -12)

Step-by-step explanation:

I like to approach this problem by finding the halfway points in the x-direction and the y-direction, separately.

x-direction:  find the average of -3 and -15, which is -18/2, or -9.  The x-coordinate of the midpoint is therefore -9.

y- direction:  find the average of -4 and -20, which is -12.

Thus, the midpoint is located at (-9, -12)   (Answer B)

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
