Step-by-step explanation:

The slope of the line is found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (-11 -1)/(2 -(-1)) = -12/3 = -4

Then the point-slope form of the equation for a line can be used to write the equation:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

Using the first point, the equation is ...

  y -1 = -4(x +1)

__

Simplifying to slope-intercept form, we can find the y-intercept.

  y = -4x -4 +1

  y = -4x -3 . . . . . . . . slope-intercept form

The constant in this equation is the y-intercept: -3, point (0, -3).
