Explanation:
The slope of the parallel line is the same as the original line, so look at the slope of the original line. y=5/4x-7. the slope is the "m" term in y=mx+b, which is 5/4.
The slope of the perpendicular line is just the negative reciprocal of the slope. the reciprocal of 5/4 is just 4/5 ("flip" the fraction to find the reciprocal). and negative 4/5 is just -4/5
