What is the slope of line m?
jimthompson5910 (jim_thompson5910):
parallel lines have equal slopes
jimthompson5910 (jim_thompson5910):
so the slope of line m is also 8/5
OpenStudy (anonymous):
i thought so just making sure
OpenStudy (anonymous):
and what if it is perpendicular

jimthompson5910 (jim_thompson5910):
you'd flip the fraction and change the sign
jimthompson5910 (jim_thompson5910):
flip the fraction 8/5 ---> 5/8
change the sign: 5/8 ----> -5/8

The slope of line l is 3/4 . Line m is perpendicular to line l.
What is the slope of line m?
so its -4/3
jimthompson5910 (jim_thompson5910):
very good
OpenStudy (anonymous):
sweeetttt

Line l is parallel to line m. The slope of line l is 4/9 .
OpenStudy (anonymous):
What is the slope of line m?
jimthompson5910 (jim_thompson5910):
you tell me
OpenStudy (anonymous):
so it is the same
jimthompson5910 (jim_thompson5910):
yep also 4/9

....

OpenStudy (anonymous):
please explain
jimthompson5910 (jim_thompson5910):
hint:
the x intercept is where the line crosses the x axis
the y intercept is where the line crosses the y axis
OpenStudy (anonymous):
ooooooo simple D

yes or not :0
jimthompson5910 (jim_thompson5910):
the x-intercept is 2, so it crosses the x axis at 2 (the "2" on that axis)
jimthompson5910 (jim_thompson5910):
similar for the y intercept
OpenStudy (anonymous):
C i mixed up the negative ..... simple mistake
jimthompson5910 (jim_thompson5910):

What is the equation of a line that passes through the point (-2, 5) and is parallel to a line with a slope of 3
OpenStudy (anonymous):
so it is like y=3x+1
