Question

Select the equation of a line that is perpendicular to the line on the graph and passes through the point (3, 2).

y = 1 over 3 x + 3
y = -1 over 3x + 3
y = 3 x + 2
y = - 1 over 3 x + 2

Answer 1

@Nnesha

Answer 2

okay again first you have to find slope of the graph

Answer 3

ok so how will i do it with this @Nnesha

Answer 4

@Nnesha

Answer 5

you can pick two points and use slope formula to find slope

Answer 6

please show me srry i am kinda rushing @Nnesha

Answer 7

okay so do you know slope is rise/run then see how many points are going up and how many points are you going right
this is another way to find slope

Answer 8

so my slope would be 3/2 right

Answer 9

nope try that again see how many points are going right side

Answer 10

how do i count the points

Answer 11

if you look at this u can where its make right triangle
nw see how any step are going right

Answer 12

3 points then @Nnesha

Answer 13

yes that's right now perpendicular slope should be ??

Answer 14

ummm idk may you show me again like you do the first time @Nnesha

Answer 15

then look at ur previous post and see what i said about perpendicular slope

Answer 16

ok

Answer 17

so -3 points @Nnesha

Answer 18

slope of graph 3/1 now flip it

Answer 19

-1/3 @Nnesha

Answer 20

right :)

Answer 21

now use slope intercept form equation
y = mx+b
replace m ,x and y by their valeus then solve for b

Answer 22

what is the value of m @Nnesha

Answer 23

m is slope that you just found

Answer 24

y =-7 @Nnesha

Answer 25

??? @Nnesha

Answer 26

y ??
suppose to b =

Answer 27

b=-7??/ @Nnesha

Answer 28

hmm nope

Answer 29

omg please just tell me @Nnesha

Answer 30

that's how you should replace
