Answer:
-5, 5
Step-by-step explanation:
The line in this problem can be written in the form
(1)
where:
is the slope
q is the y-intercept
We know that the line passes through the point (-2,5), so substituting these values into eq.(1), we find the value of the y-intercept:

So the equation of the line is
(2)
Now we know that point A has coordinates
A(x,3)
So by substituting into eq.(2), we find the missing x-coordinate:

Similarly, point B has coordinates
B(-2,y)
so substituting into eq(2), we find the missing y-coordinate:

The fraction would be 7/100 and there is 7 cents of tax per dollar.
