Step-by-step explanation:
Use formula to find the slope/gradient

(-5, -1) = (x1, y1)
(5, 11) = (x2, y2)
So,

Answer: A probability of 1 means the event is certain to happen. A probably of zero means the event is certain not to happen.
Answer:
(3.5, 4)
Step-by-step explanation:
add and then divide (x1+x2 / 2, y1 + y2 / 2) so [(1+6)/2, (3+5)/2], so (3.5, 4)
