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.
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.
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.
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.
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.
