y = -5x - 8 ;

y = 4x + 1 ;

-5x - 8 = 4x + 1 ;

-5x - 4x = 1 + 8 ;

-9x = 9 ;

x = 9/-9 ;

x = -1 ;

y = -5(-1) - 8 ;

y = 5 - 8 ;

y = -3 ;

Solution set: (-1, -3)

y = 4x + 1 ;

-5x - 8 = 4x + 1 ;

-5x - 4x = 1 + 8 ;

-9x = 9 ;

x = 9/-9 ;

x = -1 ;

y = -5(-1) - 8 ;

y = 5 - 8 ;

y = -3 ;

Solution set: (-1, -3)
