It is b because the line intersects at (0,4) and the slope decreases by 2
Use the midpoint formula
(x1 + x2/2, y1 + y2/2)
Input the corresponding numbers
(-12 +5/2, 3 + -10/2)
(-7/2,-7/2)
So, the midpoint of the line segment is (-7/2,-7/2)

Answer:a) 870
b) 435
Step-by-step explanation:
a)
number of photos to be posted =n = 30
number of web pages on which they would be posted is 2
Since the order in which the photos appear on the web pages matters,
Number of ways = 30 permutation 2
=870 ways
b)
Since the order in which the photos appear on the web pages does not matter,
Number of ways = 30 combination 2
= 435 ways
