SAT Math Question of the Day

Math Category: Geometric Slope:

Q: What is the slope of 3y + 5x - 12 = 0?

  1. -5
  2. -5/3
  3. 5/12
  4. 3/5
  5. 4

UNANSWERED.

The correct answer is B.

A: The answer is -5/3.
First solve for y.
3y + 5x - 12 = 0
3y = -5x + 12
y = -5/3x + 4
The line is now in the y = mx + b format. m is the slope of the line and b is the y-intercept. m is -5/3, so that's the slope of the line.
