X/(-5/7)+y/(2 1/4)=1
Change to improper fraction:
2 1/4=9/4

[x/(-5/7)+y/(9/4)=1](-5/7)(9/4)
x+y=-45/28

Hope this helps =)

Having a and b as -5/7 and 2 1/4 respectively, plugging in you'll have:

Changing 2 1/4 to improper fraction you'll have
[(2*4)+1]/4 = 9/4

This can be expressed as

Cross multiply 45

Standard equation of a line is
Ax + By = C
Transposing -63x +20y to the right and 45 to the left
