45 and 47
Step-by-step explanation:
Answer:
You would need 2.5
Step-by-step explanation:
You can use a porportion to solve.
(cross multiply and solve)
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b / *(-1)
13 = k * 8 + b
---------------------
-11 = - k * 7 - b
13 = k * 8 + b
----------------------
2 = k
13 = 16 + b
b = 13 - 16 = -3
y = 2 x - 3 ( y varies directly with x )
