Answer:
Tanner's score = 70
Step-by-step explanation:
Data provided in the question:
Mean value of the statistics test taken by Tanner = 80
Standard deviation = 5
Total points possible = 100
Now,
It is given that the Tanner's score was 2 standard deviation below the mean
Mathematically,
Tanner's score = Mean - ( 2 × Standard deviation )
or
Tanner's score = 80 - ( 2 × 5 )
or
Tanner's score = 80 - 10
or
Tanner's score = 70

1) slope=3 and y-int.=-5
2) slope=2 and y-int.=-6
3) slope=-6 and y-int.=1/2
4) slope=-7 and y-int.=5/2
5) slope=1/2 and y-int.=7
6) slope=3/4 and y-int.=8
7) slope=-2/3 and y-int.=-1/3
8) slope=-1/8 and y-int.=-3/8
9) slope=2/3 and y-int.=5
10) slope=-2/7 and y-int.=-1
11) slope=-3 and y-int.=6
12) slope=4 and y-int.=7
