If you are looking a graph of an quadratic equation how do you know where the solutions are?
They will be on the horizontal x axis of the graph (look for the x-intercepts).
What is the smallest number of intercepts possible for a graph of a linear equation in two variables?
One.
What are the steps to graph an equation of a line using the intercepts?
Draw the axes. Plot the two intercepts. Draw a line connecting the two points
How do you use a graphing calculator to solve quadratic equations?
Graph the equation then find the x intercepts.
How do you determine the intercepts from an equation or graph?
From the equation, the y intercept is simply determined by setting x = 0. The x intercept(s) are generally much harder to find: you will need to find the solutions of y = 0 [or f(x) = 0]. From the graph the intercepts are the coordinates of the points at which the graph crosses the axes.

One.
Does graph the equation mean plot the x and y intercepts?
No; it means draw the curve.
What does a quadratic equation graph have with a negative discriminant?
It has a complete lack of any x-intercepts.

What is the point where a graph intercepts the x-axis?
The point where a graph intercepts the x axis may have several names. It could be called an x-intercept, a root, or a solution.It is at: (x, 0).
How do you find the maximum height of a parabolic path?
If "a" is negative then the graph is a cap. Find the x intercepts. Average the two x intercepts and substitute that into the equation it will give you the y.
What is the smallest number of intercepts possible for a graph of a linear equation in 2 variables?
The graph must have at least one intercept.
Graph this equation 5x plus 10y equals 20?
for the equation:5x + 10y = 20, the two intercepts are:x = 0 , y = 2 or (0,2)y = 0 , x = 4 or (4,0)The graph is a straight line passing through the two intercepts (0,2) and (4,0)
Always use the vertex and at least points to graph each quadratic equation?
You should always use the vertex and at least two points to graph each quadratic equation. A good choice for two points are the intercepts of the quadratic equation.
