I'm pretty sure it would be <span>x - y + 1 = 0 because if you plug in one of the coordinates into each equation, this is the only one that works.
</span><span>y - x + 1 = 0
2 - 1 + 1 = 0
2 = 0 not correct
</span><span>x - y + 1 = 0
1 - 2 + 1 = 0
0 = 0 correct
</span><span>-x - y + 1 = 0
-1 - 2 + 1 = 0
-2 = 0 not correct

I believe Jessica’s rate in miles per hour is 0.9.
Step-by-step explanation:
This is a straight line equation. We only need two points to draw a straight line.
Choose two different numbers, put them into the equation instead of x, and calculate the value of y.

for x = 8

<h2>(8, 1)</h2>
for x = -8

<h2>(-8, 3)</h2>
Mark the points in the coordinate system and draw a straight line through the given points.

Answer:
Each guest would get 6 party favors.
Step-by-step explanation:
First, we find out how many party favors Amy bought. 3 bags of 12 party favors equals 36 party favors (3x12)
So, divide 36 party favors by 6 guests, and you get the final answer of 6 party favors per guest.
Hope this helps!!
