Give the equation of the line that passes through point (-5, -1) and is parallel to the line y = -1/4x- 7.

  Since the new line must be parallel to the old line, it must have a slope of -1/4 so let its equation be y = (-1/4)x + b plug in our new point (-5,1) -1 = (-/4)(-5) + b -4 = 5 + 4b b = -9/4 so y = (-1/4)x - 9/4
