Answer:
The correct option is 3.
Step-by-step explanation:
If a line passes through to points 
and 
, then the slope of line is
Given points are (4,-7) and (6,3).
The slope between given points is
On further simplification we get
Therefore the correct option is 3.

As y varies directly with x, there is a proportionality constant. As x increases by that certain constant, y also increases. We equate:
y = kx
where k = proportionality constant.
Given the condition, y = 5 when x = 4, then we solve for k:
5 = k(4)
k = 5/4 or 1.25
When y = 8, then
8 = (5/4)(x)
x = 8/(5/4) = (8)(4/5) = 32/5 or 6.4 (ANSWER)
First multiply 40 and 10 to get 400. Then multiply 400 by 8 to get 3,200.
Your answer would be: 3,200
