Line l is parallel to line m. The slope of line l is 8/5 hellllpppp

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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):

hold on another question coming you have helped me more than any of these crazy people ....

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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):

C is correct

OpenStudy (anonymous):

OpenStudy (anonymous):

B

jimthompson5910 (jim_thompson5910):

correct

OpenStudy (anonymous):

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
