Line B is \(y=-x\). When x is negative y is positive and vice versa.

GIVEN: equation of line is x = y

Anther approach is to rewrite equation in slope y-intercept form y = mx + b, where m = slope of the line, and b = the y-intercept
Take the equation x = y and rewrite as: y = 1x + 0

Aha, so the line's slope is 1, and its y-intercept is 0
Line D is the only line with a positive slope, AND line D also has a y-intercept of 0

Answer: D
