What is the equation in point slope form of the line that passes through the point (2, 6) and has a slope of 5?

y−2=5(x−6)
y+2=5(x+6)
y−6=5(x−2)
y+6=5(x+2)

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.
