Wel its kinda difficult to say but look on how much times 6 can fit into 7 which is 1 but that will be 6,so in order to become seven you need 1 which is our left over number,so in the end you will get 1 whole and 1/6 and you use the leftover number as your numerator and just leave the 6 as it was.Whoof that was long but its no nearly as long as i explain it.
To find slope, use the form y1 - y2/x1 - x2. Using these points, that would look like:
-7 - 5/-1 - 1 or -12/-2, which simplifies to 6.
The slope is 6. Hope this helps with slope.
-1/2 x 1/2 = -1x1 / 2x2 = -1/4
The answer is -1/4
