Any F(x) = P(x) + b, where b = 0 and P(x) can be factored by x.
Ex) y = 843x
y = x^32 + x^23 + 4x

How do you find the y-intercept of the graph of the equation?
Set 'x' equal to zero, and solve the remaining equation for 'y'.
What kind of lines have a slope of zero?
On the standard Cartesian graph, horizontal lines have zero slope. They all have the equation Y = a number
Why do you equate the equation to zero?
Not all equations are equated to zero, but usually we set a function equal to zero if we want to find its x intercepts, or where the graph of the function crosses the x axis.
Does a graph of a linear equation always have an x intercept?
No; if the slope is zero and it is above or below y=0 it will not have an x intercept.
How do you graph an equation in function form?
I would set up a table of values and calculate several of the values of the variables (I would try to calculate the "interesting" values setting one to zero and calculating the other(s), guessing at a maximum or minimum value etc. Then I would plot the values on graph paper.

How would you graph -3 on the numberline?
To graph a negitive . You would go three spaces back from zero.
How does one find out if an equation's graph goes through the origin?
-- Take the equation -- Set either 'x' or 'y' equal to zero -- Solve the resulting equation for the remaining variable -- If the remaining variable is then also zero, then the origin is on the graph of the function If the graph is a straight line ('x' and 'y' appear in the equation only to the 1st power), then the equation has to be in the form of a simple ratio ... like (y = Kx) or (x = Ky) or (xy = K) or (x/y = K) ... in order to go through the origin.
What is the corner point of a graph of an absolute value equation?
It is sometimes the point where the value inside the absolute function is zero.
How do you find the x intercept on a linear equation?
At the x-intercept on the graph of the equation, y=0. Take the equation, set 'y' equal to zero, and solve the equation for 'x'. The number you get is the x-intercept.

Is f(x) a function?
The zero of a f (function) is an x-value that corresponds to where the y-value is zero on the functions graph or the x-intercepts. Functions can have multiple zeroes or no real zeroes at all, depending on the equation.
How speed of zero would appear on a graph?
On a graph, a speed of zero would be represented by a horizontal line at the zero point on the y-axis, indicating no change in position over time. This would appear as a flat line running parallel to the x-axis.
What is a no solution factoring or equations?
If you have a quadratic equation and there is no x to put into the equation to get zero. The graph is like a U that is above the x axis or a cap that is below the x axis.
Does a graph of a linear equation always have an x intercept?
No; if the slope is zero and it is above or below y=0 it will not have an x intercept.
