Question

What is the equation for the line?

Answer 1

HOW TO:
* use slope intercept form

1) find the slope

      slope = rise/run (rise divided by the run)
      slope = -4/2
      slope = -2

2) find the y-intercept (just the point where the line intersects the y-axis)

        y-intercept is (0,-4)

3) use slope-intercept form:
      y = mx + b  (m stands for the slope, b stands for the y-intercept)
      y= -2x + (-4)
      y= -2x - 4

So your equation is y= -2x-4
