SAT Math Question of the Day

Math Category: Geometric Slope:

Q: What is the y-intercept of the line 8 = 2y + 3/4x?

  1. -3
  2. -3/8
  3. 3/8
  4. 3/2
  5. 4

UNANSWERED.

The correct answer is E.

A: The answer is 4.
First solve for y.
8 = 2y + 3/4x
2y + 3/4x = 8
2y = -3/4x + 8
y = -3/8x + 4
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, so that's the y-intercept of the line.
