Question

what is the slope of a line perpendicular to the line 6x + 3y = 15

Answer 1

the slope of a line perpendicular to a line would be the flipped opposite of the given slope.
so for Example, if you were given a slope of 4/3
the slope of the perpendicular would be -3/4

Answer 2

how would i show work

Answer 3

just show your work of turning given equation into slope-intercept form equation.

Answer 4

then take slope (m) and turn it into -1/m

Answer 5

if slope is m, then the slope of line perpendicular of original line is -1/m, just like example @jigglypuff314 gave you.

Answer 6

i dont understand what u guys are saying :'( . i did an additive inverse

Answer 7

ok, well first figure out the slope of the given equation :)
do you know how to do that?

Answer 8

i know like the formula for slope:
y2-y1/x2-x1

Answer 9

right?

Answer 10

that's when you're given two points :)
for when you're given an equation, you would want to get it into slope intercept form
y = mx + b
where m = slope

so solve for y from 6x + 3y = 15

Answer 11

oh. so

Answer 12

3y= 6x + 15?

Answer 13

3y = -6x + 15 :)
good, then divide both sides by 3 to get y alone

Answer 14

so
y = -2x + 5

Answer 15

yep! :D
then given y = mx + b where m=slope find the slope of
y = -2x + 5

Answer 16

-2? :D

Answer 17

correct! :)
now take the flipped opposite of it like I showed in the first comment

Answer 18

umm. idk what that means ._.

Answer 19

for Example, if you were given a slope of 4/3
the slope of the perpendicular would be -3/4

Answer 20

so. the slope is positive 2?

Answer 21

close ^_^
don't forget to flip it

Answer 22

1/2 ?

Answer 23

Correct!!! :D :D :D

Answer 24
