Answer 2

Answer:

f = 2.5b

Step-by-step explanation:

The graph shows a straight line that passes through the origin, so this is direct variation.

The standard equation for direct variation is

y = kx,

where k is the constant of variation.

In this case, we have

f = kb

We need to find the value of k.

Read one point on the graph that is easy to read since it falls on a grid intersection. For example, look at (2, 5). Each point is of the form (b, f), so for point (2, 5), b = 2, and f = 5.

Replace b with 2 and f with 5 and solve for k in the equation f = kb.

f = kb

5 = k * 2

2k = 5

k = 5/2 = 2.5

Now replace k with 2.5.

f = 2.5b

The equation is f = 2.5b
