X = 4 y = 3 4x-3y=7 x=13-3y
4(13-3y) -3y =7
52 -12y -3y =7
-15y=-45
-y=-3 y = 3
x=13-(3*3)
x=13-9
x =4
Answer:

Hannah collected more acorns
If i am doing this correct.
pick to points and use the distance formula\
Y2 - Y1
divided by
X2 - X1
so i picked the points
-2, 12
0, 3
this would mean
12-3
0-(-2)
which would be
9
2
so 9/2 it isn't possible so it would stay as 9/2 which is your answer.. C
Hope this helps.!!!!
