Find the equation of the line that contains the point (27,-11) and is parallel to the line 2x+9y=18. Write your answer in slope intercept form. HOW DO YOU DO THIS!!!!

Question

amistre64 · Answer

yay!!!

amistre64 · Answer

find the slope of the line and flip it over spank its bottom throw it down and but a negative to it

dumbcow · Answer

haha
first find slope of line 2x+9y =18
get y by itself

amistre64 · Answer

-a/b is the slope of yer line ;)

dumbcow · Answer

hold up
amistre thats for perpendicular lines, this is a parallel line

amistre64 · Answer

ack!!  they need different words for those things; those are too similar lol

amistre64 · Answer

in that case; erase the 18, fill in yer x and y and solve; then git rid of the x and y values

amistre64 · Answer

2x+9y=18  ; chuck the 18...its useless to us

2x+9y=      ; now fill in your (x=27,y=-11) and solve

2(27)+9(-11)=

amistre64 · Answer

54 -99 = -45

2x+9y=-45

dumbcow · Answer

now put it in slope-intercept form by moving 2x over and dividing by 9
9y = -2x -45
y = (-2/9)x -5
that is the equation of the line going through point (27,-11) and parallel to given line
