SAT Math Question of the Day

Math Category: Geometric Slope:

Q: The y-intercept of the line 2y - 1 = 5x + 3 is

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

UNANSWERED.

The correct answer is C.

A: The answer is 2.
First solve for y.
2y - 1 = 5x + 3
2y = 5x + 4
y = 5/2x + 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.
