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.

Graph the line y=4/3 x+1 . use the line tool and select two points on the line.

What is the slope of the line that has an equation of y equals x -3
