spose we had a point (-6,3)

move it to add 2 to the x parts to move it and flip about the x=-2+2 axis

(-4,3), now flip

(4,3),  now move it back again by shifting it to the x=0-2

(2,3)

or do you know how to determine a midpoint?

amistre64 · Answer

(x1 + x2)/2 = -2

(-6 + x2)/2 = -2

-6 + x2 = -4

x2 = 2

the distance from the line x=-2 remains the same after you flip it ....
