It is a coordinate of x and y on the coordinate plane
The origin. This is the point at which each axis is at 0.
In the same coordinate space, i.e. on the same set of axes: -- Graph the first equation. -- Graph the second equation. -- Graph the third equation. . . -- Rinse and repeat for each equation in the system. -- Visually examine the graphs to find the points (2-dimension graph) or lines (3-dimension graph) where all of the individual graphs intersect. Since those points or lines lie on the graph of each individual graph, they are the solution to the entire system of equations.
Infinitely many. Each and every point on the graph gives rise to an ordered pair.
A Scale
Each point on a line graph in 2-dimensional space can correspond to an ordered pair of values for two variables which is observed. Or, if it is a fitted line graph, it is an estimated ordered pair.
It is simply called a point on the graph, or a solution to the equation represented by the graph.
bar graph
Nothing particular. The graph of y = x2, for example, changes slope at each point on the graph.
The slope at each point on a speed/time graph is themagnitude of acceleration at that point in time.
The origin. This is the point at which each axis is at 0.
Because each vertical lines meets its graph in a unique point.
The slope of the graph of speed vs time at each point isthe magnitude of the acceleration at that point in time.
they are called error bars. It represents the amount of error associated with each data point
The slope of each point on the line on the graph is the rate of change at that point. If the graph is a straight line, then its slope is constant. If the graph is a curved line, then its slope changes.
sample space
-- Graph each equation individually. -- Examine the graph to find points where the individual graphs intersect. -- The points where the individual graphs intersect are the solutions of the system of equations.
The slope at each point of a displacement/time graph is the speed at that instant of time. (Not velocity.)
