You can put this solution on YOUR website!  is the fastest answer. You could call that the intercepts form of the equation for the line.
 If a line passes through points (a, 0) and (0, b), its x- and y-intercepts,
 then
  is an equation that represents the line. You may have been taught such a form, with that name or another name
 Since some people do not like denominators, I could multiply both sides of the equal sign times 15 to get
 
  Multiplying times other factors you can get a variety of answers.
 You can also solve for y to get the unique equation in slope intercept form
 
  -->  -->  If you had not been shown the fact that
 "if a line passes through points (a, 0) and (0, b), its x- and y-intercepts,
 
  is an equation that represents the line," then you could easily write a system of equations by plugging in the coordinates of those intercepts into
  . Solving the system would get you
  and  , and then you could write the equation in the  form.
