Answer:
3/2
Step-by-step explanation:
In order to find the slope with two points, you use this formula:
y2-y1 / x2 - x1.
y2 is 5 and y1 is -4. 5 - -4 = 9
x2 is 2 and x1 is -4. 2 - - 4 = 6
9/6 = 3/2.
Answer:
(3.5, - 3.5)
Step-by-step explanation:
Using the Midpoint theorem, we have
x=(9-2)/2=7/2=3.5
y=(-8+1)/2=-7/2=-3.5
