Answer:
y = -3x + 1
Explanation:
Rewrite 9x=3-3y in standard slope-intercept form. Start by dividing all three terms by 3, obtaining
3x = 1 - y
We want to isolate y. Adding y to both sides, we get y + 3x = 1.
Next, subtract 3x from both sides: y = -3x + 1.
This result is in slope-intercept form; the slope is 3 and the y-int. is 1.
