# ASVAB Mathematics Knowledge Practice: Slope-Intercept Form

If you’re not familiar with slope-intercept form, then you will definitely want to learn it for the Mathematics Knowledge subtest on the ASVAB. The formula for slope-intercept form is *y* = *mx* + *b*, where *m* represents slope and *b* represents the *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:
