step1:(1,-2)=>(x,y)=> x=1, y=-2

step2: substitute the values of x & y in given equation 2x-3y=8

step3:

2(1)-3(-2)=8               [(-)x(-)=(+)]

2+6=8

8=8 (LHS=RHS)

given point (1,-2) satisfies the equation 2x-3y=8, Hence (1,-2) is a solution of 2x-3y=8.

Consider lhs: 2x-3y Substitute '1' in the place of 'x' and '-2' in the place of y. Then lhs becomes : (2×1)-(3×(-2)) =2-(-6) =2+6= 8 Hence proved.
