One can also solve this by calculation:
y=2x-9
y=-2x-1
-
Rearrange either equation to find x. I'll use the first:
y=2x-9
2x = y+9
x = (y+9)/2
Now use this value of x in the second equation:
y = -2x-1
y =-2((y+9)/2)-1
y = (-2y-18)/2)-1
y = -y -9 - 1
2y = -10
y = -5
Now use -5 for y in the rearranged equation:
y = -2x-1
-5 = -2x-1
-2x = -4
x = 2
Solution is (2,-5)
But the question wants a graph solution, which is also fun when you use DESMOS.

Answer:
A refrigerator’s sole purpose is to keep things cold. Simple, right? But if you’ve ever dug through your crisper drawers to find your carrots have turned into frozen sticks, then you know the pains of having a refrigerator that’s set to the wrong temperature. And one that’s too warm can have adverse effects if your food spoils quickly.
