Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v = ← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 = ( multiply both sides by 5 )
45 = k
v = ← equation of proportion
When w = 4 , then
v = = 11.25

The equation of line graphed is,
Step-by-step explanation:
Point slope form: The straight of line in the form of :
......[1] where m is the slope.
Consider two points from the given graph:
(0, 0) and (2, 1)
First calculate slope:
Slope(m) =
Substitute the given values we have;
Substitute the given values m and (0,0) in [1] we have;
Simplify:
therefore, the equation of line graphed is,
