Plug the x-values into the original equation. If you get the same y-values, then the points are valid.

Do two points determine a plane?
No. Three points do. Two points determine a line.
What is the point at which a graph changes directions?
Turning points are the points at which a graph changes direction from increasing o decreasing or decreasing to increasing.
A line graph in which the data points do not fall along a straight line is called?
nonlinear graph
What is the minimum number of points needed to identify a line?
Two. Two points determine a line. Three points determine a plane.
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.
How can you tell if a graph is a function?
A graph is a function if every input (x-value) corresponds to only one output (y-value). One way to check for this is to perform the vertical line test: if a vertical line intersects the graph at more than one point, the graph is not a function.
What are the steps in plotting a line graph?
There are seven steps which are: 1. Identify the variables 2. Determine the variable range 3. Determine the scale of the graph 4. Number and label each axis 5. Plot the data points 6. Draw the graph 7. Title the graph
How do you determine whether a graph of a mathematical relationship is a function?
If a vertical line, within the domain of the function, intersects the graph in more than one points, it is not a function.
How do you determine the slope of a line on an graph?
Rise divided by run. (Y2 - Y1) / (X2 - X1) - with (X1, Y1) and (X2, Y2) being two points on the graph.
How do you determine weather the graph represent a function?
The "vertical line test" will tell you if it is a function or not. The graph is not a function if it is possible to draw a vertical line through two points.
How do you graph points?
To graph points, use rise over run and go up and over on the graph
What line test is used to determine if a graph is a 1-1 function?
2
What information can you determine from a bar graph that you cannot determine from a circle graph?
asha
How can you tell if a function is a function?
The vertical line test can be used to determine if a graph is a function. If two points in a graph are connected with the help of a vertical line, it is not a function. If it cannot be connected, it is a function.
What is a graph of isolated points?
It is a graph of isolated points - nothing more, nothing less!
The end points are what on a graph of an inequality?
points
What is a graph of distinct points called?
A scatter graph.
