You only need two separate ordered pairs for the slope formula
1st element can be matched with 5
2nd element can be matched with 4
3rd element can be matched with 3
etc.
Total number of correspondences = 5*4*3*2*1 = 120
Answer:
y = 2x - 1
Step-by-step explanation:
(4,7) (2,3)
slope = (7-3)/(4-2) = 4/2 = 2
y = 2x + c
when x=4 , y=7
7 = 2(4) + c
c = 7-8 = -1
y = 2x - 1
