(6,-1) 8x-7y=5

OpenStudy (anonymous):

hmm?

OpenStudy (lgbasallote):

equation of the line?

OpenStudy (anonymous):

write an equation of the line containing the given point and parallel to the given line

OpenStudy (anonymous):

parralel means the slope of the new line must be the same

OpenStudy (anonymous):

find the slope of the origional line first

OpenStudy (anonymous):

all i know is you subtract 8x from both sides, then divide both sides by -7 to isolate y. I get 8/7x + b, but I never get the "b" part right

OpenStudy (anonymous):

ok but any line with the slope 8/7 with any b will be parralel to the origional

OpenStudy (anonymous):

by the way the origional b is -5/7

OpenStudy (anonymous):

oh ok and the new line neeeds to contain that point 6,-1?

OpenStudy (anonymous):

so ur m is 8/7 take a point (6,-1) which gives you an x and a y and then\[-1=\frac{8}{7}(6)+b\]

OpenStudy (anonymous):

solve for b

OpenStudy (anonymous):

all lines have form y=mx+b

OpenStudy (anonymous):

If you know y m and x you can find b no probs

OpenStudy (anonymous):

48/7?

OpenStudy (anonymous):

\[(-1)-\frac{48}{7}=b\]

OpenStudy (anonymous):

-55/7

OpenStudy (anonymous):

ah! THANK YOOOOUUU

OpenStudy (anonymous):

sometimes answers dont always look pretty

OpenStudy (anonymous):

Do you get the method I explained though?

OpenStudy (anonymous):

i guess not bc i have another similar question And i still got the answer wrong

OpenStudy (anonymous):

nope, got it!

OpenStudy (anonymous):

Ok so let me take my time to explain

OpenStudy (anonymous):

great :P

OpenStudy (anonymous):

medal my answer :)

OpenStudy (anonymous):
