It's called theta and it's a Greek letter.
Typically, with hand written documents, the number zero will be indicated as a circle with a slash through it.
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.
Since the line is horizontal, the slope is zero.
y = 7
Displacement of a straight line is zero...
Izzy and Amie made the zero with a line through it!
I and A!
How about "is always zero"?
to separate the negative numbers and the positive numbers on a number line
sometimes zero
A straight line passes through the x-axis one time, if its slope is non-zero, or not at all, if its slope is zero.
The line going through an "o" helps to clarify the letter o, from the number zero.
Greenwich, England
The symbol is a zero with a diagonal line through it.
zero
This is the Zero line of longitude that passes through Greenwich Observatory in London, England.
y = 0. You can get this from the slope-intercept equation of the line.
