City A = x
City B = y
1st equation: 4x-8 =3y
2nd equation: x-2y = -3 , rewrite as x = 2y-3
replace x in eq. 1 with equation 2
4(2y-3) -8 =3y
8y-12-8=3y
8y-20 = 3y
-20 = -5y
y = -20/-5 = 4
x = 2y-3 = 2(4)-3 = 5
City A was 5° C, and City B was 4° C.
Two of the given points have the same y-value. The midpoint of those two will be on the line of symmetry, as is the vertex. The x-value there is (-1+5)/2 = 2.
3+4+8+5+2+0+5+3+4+3+7=49
49+12= 4.1 mean
