Select the description that is true of the equation y=-5x+5 .
slope = 5
slope = 1/5
y-intercept equals 5
y-intercept equals -5

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.
