The slope of a line is 9. What is the slope of line that is parallel to it?
The slope of a line is 9. What is the slope of line that is perpendicular to it?
+36916 Parallel lines have the same slope
Perpindicular lines : If a line has slope 'm' the perpindicular slope is - 1/m
so if slope m = 9 perpindicular would be - 1/9
