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

  1. What is y + 3x – 6 = 0 in slope-intercept form?

    A. y = 3x + 6 B. y = –3x + 6 C. y = –3x – 6 D. 6y = –3x

  2. Rewrite in slope-intercept form:

    x + y + 9 – 4x + 2y = 0
