Question

What angle line y=x makes with positive x-axis?

Answer 1

45°

Answer 2

That the only one?

Answer 3

Yes, how would a line make two angles with the x axis?

Answer 4

The acute angle is 45 degrees.

Answer 5

The obtuse angle is 135 degrees.

Answer 6

Draw two linex that intersect at a point. Thost lines divide the plane into four regions.

Answer 7

I'd be inclined to say -135 degrees?

Answer 8

The angle would be 45° because when you measure angles to the x-axis, you measure from the positive side.

Answer 9

OK, 45 and 225 then?
