Question

Find the slope of every line that is perpendicular to the graph of the equation - y+2x=6

Answer 1

Slopes of perpendicular lines multiply to give -1.

Answer 2

perpendicular means slope is negative inverse.. calculate the slope and find it's negative inverse.

Answer 3

so replace -1 with x?

Answer 4

Okay look:
-y +2x = 6
-y = -2x+6
y = 2x-6
Slope of ur original equation is 2

Answer 5

In other words, slope of line * slope of perpendicular line(s) = -1

Answer 6

Now to get the slope of perpendicular line do:
-1/2

Answer 7

ax + by = c is the format that you are looking at here; where the slope of this line is -a/b

a perpendicular line to this one will have a slope of b/a

Answer 8

i dotn get it :(!

Answer 9

OK, which bit?

Answer 10

everything :( i need help step by step.

Answer 11

Okay look:
-y +2x = 6
-y = -2x+6
y = 2x-6
Slope of ur original equation is 2

Answer 12

So M=2 to get the perpendicular slope do -1/M = -1/2

Answer 13

-y + 2x = 6 is a line.

If we put this equation in a standard way, we can just "read" the slope from it.

Answer 14

ok but is asking to find the perpendicular graph of the equation using y+2x=6 :(

Answer 15

y or -y?

Answer 16

Your question says -y?

Answer 17

y or -y? good question.. please post the correct question.

Answer 18

its y! lol look.

Answer 19

yea well ur original question said -y..

Answer 20

OK, when you put the questions, don't use a dash, people will think it is a - sign.

Answer 21

Okay look:
y +2x = 6
y = -2x+6
Slope of ur original equation is -2

Answer 22

Slope of perpendicular line is (-1)/(-2) = 1/2

Answer 23

Go a little bit slower, bahrom..

Answer 24

im sorry :( dont yell at me. so the answer is 1/2 ?

Answer 25

yes and estudier how much slower can i go? that;s already like every step.

Answer 26

you have:

a x +b y; slope = -a/b
+2x +1 y slope = -2/1

perp line has slope of b/a: 1/2

Answer 27

thanks dolllll <3

Answer 28

scilaaaax3, do you understand how to read the slope from an equation now?
