Answer:
you have to use the slope equation, which is (y2-y1) / (x2-x1)
3. (5-0)/(1 -(-8))
5/1+8
5/9
4. (3-3)/(-4 -8)
0/-12
the slope is 0
6. (-2-8)/(1-0.5)
-10/0.5
-20
7. (7-(-1))/ (4-4)
7+1/0
8/0
the slope is undefined
I’m not sure but since no one else commented I would think it’s D, I think you take the first number like 6 for a and subtract the first number for b like 3
keeping in mind that when the logarithm base is omitted, the base 10 is assumed.
All of the above are true
