The lines shown below are perpendicular. if the green line has a slope of -1/4, what is the slope of the red line

  4

Step-by-step explanation:

You can read the slope of the red line from the graph. It has a rise of 4 for a run of 1, so has slope 4/1 = 4.

__

You also know that the slope of a perpendicular line will be the negative reciprocal of the slope of the given line:

  -1/(-1/4) = 4

The slope of the red line is 4.

but which class are u may know that first
