Question

The y-intercept of the equation y=-4x-5 is ______.

  1. -4
  2. -4x
  3. 5
  4. -5

Hint:

to get intercept substitute x = 0 .and solve for y.

The correct answer is: -5


    The slope-intercept form of equation of a line is y =mx +b
    Given line is y= -4x-5
    Substitute x = 0
    y= -4(0) -5
    y= -5

    if equation is in the standard form, then constant term c will be y's intercept.
    slope intercept form is y = mx + c.
