The graph shows the relationship between the late fines the library charges and the number of days late

Step-by-step explanation:

We are given that a graph which shows the relationship between the late fines the library charges and the number of days late.

From given graph we can see that

The graph passes through the points (2,0.5)  and (10,2.5).

We have to find the equation for the relationship.

Slope formula:

By using the formula

Slope of graph=

Slope of graph=m=

Point slope- form:

We have

Substitute the values then we get

The equation of for the relationship

Hence, the equation for the relationship is given by

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
