Any real number will work with the equation y=x
X=x; a=6
x^2 + x^2 = 6^2 (pythagorean theorem)
2x^2 = 36
x^2 = 36/2 = 18
x = square root of 18
x = 2.62 (to the nearest hundredth)
When you reflect over the y-axis, you negate the x coordinate and maintain the same y coordinate.
so (a,b) reflected over the y-axis would be (-a,b).
