What’s the domain of this function? fastttt

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)

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.
