If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line...:)
Answer:
(-1, -5)
Step-by-step explanation:

1. We must calculate x, for that we must substitute y, so we have:
5x=9x+4
2. Now we solve the equation.
5x-9x=4
-4x=4
x=-1
3. Now we must calculate y
y=5x
y=5(-1)
y=-5
And the answer is (-1, -5)
The interior angle measures are 900 degrees
131+122+125+148+107+126 = 759
900-759 =141
X = 141
I got x = 4.3 (I cant type it but there’s a line above 3 which means there’s no end)
