What is the slope-intercept form of this equation? 3x + 9y = 18 A. y = -1/3x + 6 B. y = -1/3x + 2 C. y = 1/3x + 6 D. y = 2/3x + 2

Question

campbell_st · Answer

subtract 3x from both sides of the equation. 

then divide both sides by 9. 

this will put the equation in slope intercept form.

campbell_st · Answer

3x + 9y = 18
 -3x            -3x
-------------------
            9y = -3x + 18

now divide every term by 9

anonymous · Answer

9 / 9 =1   -3 / 9 = -0.333333333333333 @campbell_st

campbell_st · Answer

can you simplify -3/9 and leave it as a fraction

campbell_st · Answer

and if you divide the constant by 9 the answer should be obvious
