Yes, because the line crosses the y-axis at the origin and the y-value at that point is 0. Therefore, the y-intercept is zero and this equation for this line would be y=x.
The slope is -5. The x- and y-intercepts are both zero. In other words, it passes through the origin.
Typically, with hand written documents, the number zero will be indicated as a circle with a slash through it.
It's called theta and it's a Greek letter.
Since the line is horizontal, the slope is zero.
y = 7
sometimes zero
Yes.
y = 0. You can get this from the slope-intercept equation of the line.
A straight line through the origin, with a finite non-zero slope.
the origin
its called the origin
Izzy and Amie made the zero with a line through it!
Indeed no. It is only by convention and for convenience we use zero as the origin. But for example -273 C (absolute zero) could be a starting point in low temperature physics.

positive numbers
I and A!
y=ax is a line that goes through the origin. If a is negative the left side is up. If it is zero it is level. If it is positive the right side is up.
