#343y+252x=495#

Explanation:

To find the equation of the line with slope #m=-36/49# and passing through point #(26/7,-27/21)#, we use point slope form of equation, which is given by

#(y-y_1)=m(x-x_1)# which, given slope and point #(x_1,y_1)#, is

#(y-(-27/21))=(-36/49)(x-26/7)# or

#y+27/21=-36/49x+36/49xx26/7# or

#y+27/21=-36/49x+936/343#

Now multiplying each term by #343# , we get

#343y+(49cancel(343)*9cancel(27))/(1cancel(21))#

=#-7cancel(343)*36/(1cancel(49))x+1cancel(343)*936/(1cancel(343))#

or #343y+441=-252x+936# or

#343y+252x=936-441=495#
