Select the correct answer. What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)? A. y = 3x + 4 B. y = 3x − 14 C. y = 3x − 4 D. y = 3x + 12

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.
