The conditions for this problem are improperly stated in my view. The intercepts of a line are points which are properly described with ordered pairs (assuming that you are working in 
space) rather than scalar constants.
Hence, the conditions of the problem should have been 
-intercept: )
and 
-intercept: )
Use the two-point form of an equation of a line:
(x\ -\ x_1) )
where )
and )
are the coordinates of the given points.
Do the arithmetic and simplify to the point-slope form:
 )
and the slope-intercept form:

Haven't heard of the point-slope form, but I'll give you the three basic forms:
I Slope-Intercept Form is y = m*x + b, where m is the slope and b is the y-intercept
II Standard Form is A*x + B*y = C, where A, B, and C are constants and
III Intercept Form is x/(x-int) + y/(y-int) = 1, where x-int is the x intercept and y-int is the y intercept.
The third one is the easiest for you to start with because the x-int and y-int are given. Substituting them into III yields
(1) x/(-1/9) + y/(7) = 1
Simplifying (1) gives us
(2) -9*x + y/7 = 1 or
(3) -63*x + y = 7, which is the standard form II.
Solving (3) for y yields
(4) y = 63*x + 7, which is the slope intercept form.
Take your pick!
