Answer:

(-1,-2)

Step-by-step explanation:

There is a solution where the two expressions intersect. We can plug in what we know in the first equation in the second.

x= -1

y=3x+1

y= 3(-1)+1

y= -3+1

y= -2

Plugging y value in the equation to find x:

-2=3x+1

-3=3x

x= -1

Therefore, the point is (-1,-2)

<em>I hope this helps! :)</em>
