1st equation x - 7 < 14:
x < 14 + 7 (add 7 to both sides)
x < 21 (add 14 + 7 so it can equal 21)
2nd equation x + 13 > 21:
x > 21 - 13 (subtract 13 from both sides)
x > 8 (subtract 21 - 13 so it can equal 8)

If you are trying to find the slope of a line that is perpendicular to another line, you would need to change the sign and change it to the fraction's reciprocal.
m = 
Change the sign of the slope:

Finally, make the reciprocal of the original slope (switching the numerator and denominator):

Simplify:
