Find the midpoint of the line segment with the given endpoints. 1. (-6,3) and (-6,-1)
2. (-3,-1) and (0,9)

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
