What is the length of the line segment in the x-y plane with end points at (-2,-2) and (2,3)?
can anyone explain me how to make this one step by step?

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.
