Question

What is the slope of the line whose equation is 3x + 6y = 9?

A. -3


B.-1/2



C.1/2


D.6

Answer 1

solve for y \[y=(-1/2) x+3/2\]

Answer 2

3x + 6y = 9
-3x -3x

6y = -3x + 9
/6 /6 /6

y = -3/6x + 1.5

y = -1/2x + 1.5

Answer 3

@perdomo.arturo you're not suppose to give out answers. Guide.

Answer 4

but how do i figure out x

Answer 5

What do you mean x?

Answer 6

you have y= -1/2X - 1.5 how do i find x

Answer 7

+1.5*

Answer 8

x is your slope. y = mx + b

Answer 9

im still confused

Answer 10

@tHe_FiZiCx99 I didn't give the answer. I solved for y and assumed broklinngaylee new how to get the slope from there

Answer 11

What I mean is M is the slope. So -1/2x is your slope. B is they y intercept. In this case its 1.5. You would plot 1.5 on the y axis.

@perdomo.arturo she's asking because she doesn't understand. So you guide her through it.

Answer 12

okay but i dont have graph paper and it doesnt give me a graph on the question its through k12

Answer 13

okay i get it now thank you both!!!:)

Answer 14

No you don't need it, they're just asking to find the slope (M) of the given equation. They put it in standard form (Ax + By = C) so you had to convert it to slope intercept form.

Answer 15

okay! thank you for guiding me through this problem i understand it now!:)

Answer 16

Yw!
