If there is 10% of $18 = 18 x 0.9 (1 - 0.1) = $16.20
Therefore the pie costs $16.20
He is saving 18 - 16.20 = $1.80
Line of symmetry is the line which cuts the figure into two same halves
or we can say that which passes through the figure such that it makes one half the mirror image of the other half
So we can see from the figure that y=-2 is the line which cuts the figure in to equal halves
So
y=-2
Third option
I believe it is the first option. Hope this helps!

x + 60 = 180
x = 180 - 60
x = 120°
