*y*-intercept.

## Practice questions

- What is
*y*+ 3*x*– 6 = 0 in slope-intercept form?**A.***y*= 3*x*+ 6**B.***y*= –3*x*+ 6**C.***y*= –3*x*– 6**D.**6*y*= –3*x* - Rewrite in slope-intercept form:
*x*+*y*+ 9 – 4*x*+ 2*y*= 0

## Answers and explanations

- The correct answer is
**Choice (B).**The formula for slope-intercept form is

*y*=*mx*+*b*, with*m*representing the slope and*b*representing the*y*-intercept. Isolate*y*: - The correct answer is
**Choice (D).**The formula for slope-intercept form is

*y*=*mx*+*b*, so combine like terms and isolate*y*:Simplify the equation by dividing each term by 3:
