SAT Math Question of the Day

Math Category: Geometric Slope:

Q: The y-intercept of the line 6x - 3y = 4 is

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

UNANSWERED.

The correct answer is A.

A: The answer is -4/3.
First solve for y.
6x - 3y = 4
-3y = -6x + 4
y = 2x - 4/3
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 -4/3, so that's the y-intercept of the line.
