Question 1062271

what is the angle derived from the equation x=y in the positive direction of x axis
<pre>The line, x = y is a positive one in the 3rd and 1st quadrants, but the positive direction of the x axis is the 1st quadrant.
The "y" and "x" axes form a {{{90^o}}} angle in all 4 quadrants, and the line x = y, bisects this {{{90^o}}} angle, thereby forming an angle that is: {{{highlight_green(matrix(1,3, 90^o/2, or, 45^o))}}}
