Answer:
1/7x or 1/7
Step-by-step explanation:
the equation for slope is
y2-y1 over x2 minus x1, so basically it means that you find the second x which in this case is 12 and subtract the first x which is 5. 12-5 is 7
You also do -7 minus -6 for the y2-y1 stuff so it is -7 plus 6 cuz the double - signs cancel out to positive.
-7 + 6 is 1
1 over 7 is 1/7
