Answer:
-11 yards
Step-by-step explanation:
the first loss is represented by -4 and the second loss is represented by -7.
The sum of negative numbers will be:
(-4) + (-7) = -11
3*3 = 9
2*6 = 12
1*1 = 1
9+12+1 = 22
The Giants would score 22 points if Tom is correct
Given parameters:
Midpoint of AB = M(3, -1)
Coordinates of A = (5,1)
Unknown:
Coordinates of B = ?
Solution:
To find the mid point of any line, we use the expression below;
and 
where
and
= coordinates of the mid points = 3 and -1
x₁ = 5 and y₁ = 1
x₂ = ? and y₂ = ?
Now let us input the variables and solve,
3 =
and -1 = 
5 + x₂ = 6 -2 = 1 + y₂
x₂ = 1 y₂ = -2 -1 = -3
The coordinates of B = 1, -3
