x=2
y=-3
Answer:
8/4
Step-by-step explanation:
to do slope is y2 - y1 over x2 - x1, so it would be 11 - 3 for 8, then 6 - 2, leaving 8/4.
17/20 is 85% in its simplistic form... first put 85/100 and then divide both numerator and denominator by 5.
Answer: 17
Step-by-step explanation: You need to subtract 15 by 32 to get 17.
