zero
The positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative (not zero).
The horizontal axis can be used with zero where the axes meet. usually the positive are to the right and negative to the left. but any axis can be used if defined as such.
Very cold, usually snow and ice on the ground. Just kidding A line that is 30 degrees below zero is 1/3 the distance between the X and the Y axis (the line is closer to the X than the Y axis), with all the X values being positive and the Y values being negative.
It is not possible to answer the questions since there is no such thing as a zero axis.

With difficulty. Plot a graph of the polynomial and see where it crosses the x axis. If it does, then y=0 at that point, and (x-a) is a factor. Sometimes you might spot where the polynomial is zero just by trying various values.
in a graph, a line with a zero slope is the one that is parallel to the x-axis. It is represented by an equation of the form y = a constant, independent of x values.

when you have a function lets say y = mx + b then you set it equal to zero and solve you are finding the x values that give you a y value of zero and a y value of zero lies on the x-axis. therefore when you find a zero of a function it's really the x value of where the function touches or crosses the x axis. hope this helps
The y-axis has the equation x=0, so every point on the y-axis has an x coordinate of zero.
Because, in order for the equation to cross the x-axis (for example), the y-value must logically be zero. Otherwise the point that you find would not be along the x-axis; e.g if y=1, the point would be above the x-axis, or if y=-2, the point would be below the x-axis, rather than the intercept on the x-axis. I.e to plot co-ordinates, you always plot x (across), the y (up or down). To find the x intercept, you need to know how much "across" it is, but you don't want it to be "up or down", since then it won't be the intercept. This is why 'y' must be zero. The argument is the same for plotting y-axis intercepts.
1 over surd x has no value since surd is not specific. In any case, you select a set of values for x from within the domain. Calculate the corresponding values of y and then plot each pair (x, y). Then, after checking that the denominator of the function does not become zero anywhere, you join the points by a smooth line. If the denominator does become zero, you select values for x close to where it does, calculate y and plot these as best you can. The graph will have a discontinuity where the denominator is zero.
it is zero if you are given two points on a line, you can find the slope by subtracting the y values then put that over the difference of the x values but subtract them in the same order like 0-0 divided by 0-3
