For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
According to the data of the statement we have to:
Then, the equation is of the form:
We substitute the pointand find "b":
Finally, the equation is:
To graph we place the points and
on the coordinate axis and join the points by a line.

Answer:
35 purses
Step-by-step explanation:
Set up a proportion, where x is the number of purses she can make in 28 hours:
=
Cross multiply and solve for x:
8x = 280
x = 35
So, in 28 hours, she can make 35 purses
