distance and midpoint?

Question

Consider the two points (5,y0) and (-9, y1)

 

1.) Compute the distance between these two points in terms of y0 and y1.

 

2.) Compute the midpoint of these two points in terms of y0 and y1.

Answer 1

distance = sqrt(( 5+9)^2+(y_0-y₁)^2)

 

midpoint =(-9+5)/2 , (y₁+y₀)/2
