Write the equation of the line that passes through the points (−7,1) and (7,-6). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

The answe i think is 23

  example you can find the perimeter by addig all of its respective sides as such: (12+x)+(12+x)+(7+y)+(7+y).  adding like terms will result in   2x+2y+38    if you chose  xy+7x+12y+84, you multiplied the two sides to find the area.  if you chose  x+y+19
