The points (2, 100) and (4, 105) are found on a line. Which function models the relationship between the two points?

A y = -0.4x + 100.8

B y= 0.4x + 103.4

C y= -2.5x + 105

D y= 2.52 + 95

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.
