Solve the system of equations using substitution or graphing.

Step-by-step explanation:

I think substitution would be the easiest since you already have one of the variables solved for.

(You can just set the equations equal to each other since they both equal y).

Now, to get the points, plug in x = 4 and x = -1 into one of the equations (I'm going to plug them into y = x+1 because that one is much simpler)

So, your final points are:

(4,5) and (-1,0)

where are the images of the functions i can only see the question you typed.
