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.
- 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
- Rewrite in slope-intercept form:
x + y + 9 – 4x + 2y = 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:
