I need help solving these two problems, I'm stumped on them!  Thanks, guys!

1. Find the equation of the line passing through the points (-1,5) and (2,5).  Write the equation in point-slope form, slope-intercept form, and standard form.

2. Find the slope of the line containing the pair of points.  (5,-5) and (7,-2).

1.
y = 5

2.
m = (-2 + 5 ) / ( 7 - 5 ) = 3/2

1).  Point-slope:  y1 - y = m(x1 - x)
           5 - 5 = m(2 + 1)
            y - 5 = 0  

     Slope-intercept form:   y = mx + b

          y = 0x + 5
           y = 5
         
    Standard form:    Ax + By = C
 
      0x + 1y = 5
       y = 5

2)  m = (y - y1)/(x - x1)
     m = (-5 + 2)/(5 - 7)
     m = -3/-2
     m = 3/2
