You might start with the intercept form for the line
If x/a + y/b = 1
then the x- and y- intercepts are at (a,0) and (0,b)
So, your line can be expressed as
3x - 7y = 30
x/10 - y/(30/7) = 1
So now you can easily find A.
B is the intersection of your line and the line y=x, which bisects the angle between the axes.
