Solution for y-9=5/7x-5/7(x-2) equation: 


x in (-oo:+oo)

y-9 = (5/7)*x-((5/7)*(x-2)) // - (5/7)*x-((5/7)*(x-2))

(5/7)*(x-2)-((5/7)*x)+y-9 = 0

(5/7)*(x-2)+(-5/7)*x+y-9 = 0

5/7*(x-2)+(-5*x)/7+y-9 = 0

(5/7*7*(x-2))/7+(-5*x)/7+(7*y)/7+(-9*7)/7 = 0

5/7*7*(x-2)-5*x+7*y-9*7 = 0

7*y-63-10 = 0

7*y-73 = 0

(7*y-73)/7 = 0

(7*y-73)/7 = 0 // * 7
