Answer:

  • m = -3/4
  • y-intercept = 399
  • slope-intercept equation: y = -3/4x + 399

Step-by-step explanation:

It can be easiest simply to solve the equation for y.

  3x + 4y = 1596

  4y = -3x + 1596 . . . . subtract 3x

  y = -3/4x + 399 . . . . divide by 4

From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
