Question

Graph 3x + 6y = 18

Answer 1

first convert to y = mx + b

Answer 2

first you have to simplify 3x + 6y = 18
3x + 6y = 18
6y=-3x+18
y=-3/6x+3

Answer 3

so you have 3x + 6y = 18
6y = -3x + 18
y = -3/6 + 18/6

so y = -1/2x + 3

Answer 4

You guys do realize that standard form is the fastest way to get two intercepts and easily determine the line?

Answer 5

now you have that the y-int = 3 and it is a negative slope

Answer 6

we can tell the graph will be negative because the x is negative so b and c is out

Answer 7

So a

Answer 8

you can find the x-intercept to see where the line cross on x so when y = 0 you have
3x + 6(0) = 18
3x = 18
x = 6, so it cross on (6,0)

Answer 9

yes its a because y=-3/6x+3, 3 is the y axis and and choice a is negative and has a y axis of 3.

Answer 10

or, you guys can completely ignore my advice. :<

Answer 11

sorry, this is jst the way I do it :)
