SAT Math Question of the Day

Math Category: Geometric Slope:

Q: What is the y-intercept of the line 3(y + 4) + 2(x - 3) = 0?

  1. -6
  2. -2
  3. -2/3
  4. 2/3
  5. 2

UNANSWERED.

The correct answer is B.

A: The answer is -2.
First solve for y.
3(y + 4) + 2(x - 3) = 0
3y + 12 + 2x - 6 = 0
3y = -2x - 6
y = -2/3x - 2
The line is now in the y = mx + b format. m is the slope of the line and b is the y-intercept. b is -2, so that's the y-intercept of the line.
