How do you interpret a line graph?
The horizontal label across the bottom and the vertical label along the side tells us what kinds of data is being shown. The horizontal scale across the bottom and the vertical scale along the side tell us how much or how many. The points or dots on the graph represents the x,y coordinates or ordered pairs.
How do you describe the trend of a line graph?
The y-value of each point generally increases as the x-value increases. We can add a trend line to this graph by adding a line that goes through the middle of the points. Notice that the trend line has a positive slope.
What is a line graph and what is it used for?
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
How do you plot two lines on the same graph in Excel?
Select all the data you want to graph, click the “Insert” tab, and then select the chart type and sub-type you want to plot. The chart should show a separate plot for the first and second data series on a common Y axis.
What is an XY graph?
Also called: scatter plot, X-Y graph. The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the tighter the points will hug the line.
What is the other name of XY chart?
SCATTER PLOT OR SCATTER GRAPH IS ANOTHER NAME OF XY CHART.
Where is y axis on a graph?
The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
What are vertical lines on a graph called?
The vertical line in the given graph is called Y-axis. In the Cartesian coordinate system, the vertical reference line is called Y-axis.
How do vertical lines look?
A vertical line is a line, parallel to y-axis and goes straight, up and down, in a coordinate plane. Whereas the horizontal line is parallel to x-axis and goes straight, left and right.
What is the name of horizontal and vertical lines?
Sol: (i) The name of horizontal and vertical lines drawn to determine the position of any point in the Cartesian plane is x-axis and y-axis respectively. (ii) The name of each part of the plane formed by these two lines x-axis and y-axis is quadrants. (iii) The point where these two lines intersect is called origin
What is the difference between horizontal and vertical line?
A vertical line is any line parallel to the vertical direction. A horizontal line is any line normal to a vertical line. Vertical lines do not cross each other.
Which is the horizontal line?
The meaning horizontal line is a straight line that is mapped from left to right and it is parallel to the X-axis in the plane coordinate system. In other words, the straight line that does not make any intercept on the X-axis and it can have an intercept on Y-axis is called horizontal line.
What is the name of each part of the plane formed by the two lines?
Answer. The name of each part of the plane formed by these two lines x-axis and y-axis is quadrants. The point where these two lines intersect is called origin
What is the name of point where two lines intersect?
Answer. The point is called intersection point
What are the coordinates of any point lying on Y-axis?
If a point lies on the x-axis then its y-coordinate is 0. Similarly, a point on the y-axis has its x-coordinate 0. The origin has coordinates (0,0)
What is the name of each part of the plane formed by horizontal and vertical lines?
Answer: Horizontal line is called x-axis and Vertical line is called y-axis. Each part of the Cartesian plane formed by x-axis and y-axis is called quadrant
What is the name of the point where horizontal and vertical lines intersect?
origin
