A linear function in general form is given below. Find the equation of the line that is parallel to it and passes through `(-6,-8)`. Also, find the equation of the line that is perpendicular to it and passes through the point `(4,-2).` Write both equations in general form. Sketch the graphs of all three lines on the same coordinate plane.
`2x-6y-42 = 0`
The equation of the line, in general form, that passes through `(-6,-8)` and is parallel to the given line is:
The equation of the line, in general form, that passes through `(4,-2)` and is perpendicular to the given line is:
Sketch the graphs of all three lines and the two given points.
