If two lines in the standard (x,y) coordinate plane are perpendicular, and the slope of one of the lines is -5/7, what is the
slope of the other line ?
A.) 7/5
B.) 5/7
C.) -5/7
D.) -7/5
E.) -5
slope of the other line ?
A.) 7/5
B.) 5/7
C.) -5/7
D.) -7/5
E.) -5
Perpendicular lines have slopes which are negative reciprocals of each other. For example: 3/4 and -4/3.
Parallel lines have equal slopes.
If the slope of one of the perpendicular lines is -5/7,
the slope of the other line would be 7/5. {the negative reciprocal of -5/7}
A.) 7/5
