Question

what is the solution of the system? Use the graph. y=x+5 y=-5x-1

Answer 1

y = x + 5 
y = -5x -1

so than you make y = y so x + 5 = -5x -1 result 6x = -6 so x = -6/6 so x = -1
and than you check it 

y = - 1 +5 = 4
and 
y = - 5 *(-1) -1 = 5 -1 = 4

so this mean that - 1 is the solution of the system sure
