We have a constant function, f(x) = 4.
For all the values of x, the value of the function is constant and equal to 4.
The function has only one y intercept at (0, 4) and no x intercept.
Since the value of the function is

We need to find the line y= mx +b to y=-2x-4; that passes through (2,-3)
When a line is parallel to another line, both lines then have the same slope. I will use the ordered
