Hello : 
<span>
 y=5x+8
y= -4x-1 
5x+8 = -4x-1
9x =-9
x = -1 
y = 5(-1)+8 = 3 
</span><span>ordered pair is the solution to the system : ( -1 , 3)</span>

Answer:

(-1,3)

Step-by-step explanation:

y=5x+8 , y=-4x-1

Both sides have y on the left hand side so make the right hand side equal and solve for x

5x+8= -4x-1

To solve for x , add 4x on both sides

9x+8=-1

Subtract 8 on both sides

9x=-9

Divide by 9 on both sides

x=-1

Now plug in -1 for x in the first equation and find out y

y=5x+8

y=5(-1)+8

y=-5+8

y=3

Ordered pair is (x,y) that is (-1,3)
