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

Answer 1

3x+9y=18

Divide by 3 to put equation in simplest form

X+3y=6

Divide by 3 again so Y has no coefficients

1/3x+y=2

Subtract x so y is on its own side

ANSWER

Slope int. Form is y=mx+b

So the answer would be

Y=-1/3x+2
