What is a line graph BBC Bitesize?
A line graph is often used to show a trend over a number of days or hours. It is plotted as a series of points, which are then joined with straight lines. The ends of the line graph do not have to join to the axes.
What is a line graph Year 4?
A line graph is a graph used to show changes over time, for example changes in temperature through a day. It is created by plotting points and joining them with straight lines.
What is a line graph Year 5?
What is a line graph? A line graph is used to display continuous data, which is data that changes over time. A line graph has two axes. The horizontal axis (x-axis) shows the time data (for example, time in minutes or days).
What is line graph in physics?
Linear means straight and a graph is a diagram which shows a connection or relation between two or more quantity. So, the linear graph is nothing but a straight line or straight graph which is drawn on a plane connecting the points on x and y coordinates.
What is the meaning of line graph?
A line graph is a graphical display of information that changes continuously over time. Within a line graph, there are various data points connected together by a straight line that reveals a continuous change in the values represented by the data points.
What is a line graph used for?
A line graph is often used to show a trend over a number of days or hours. It is plotted as a series of points, which are then joined with straight lines. The ends of the line graph do not have to join to the axes.
How do you find the equation of a straight line graph?
Equations of other straight line graphs The equation of a straight line on a graph is made up of a (y) term, an (x) term and a number, and can be written in the form of (y = mx + c). The slope of the line is known as the gradient and is represented by the value of (m) in the equation.
What do the horizontal and vertical lines mean on a graph?
The horizontal line is called the x axis and the vertical line going up is the y axis. Both are labelled so you know what is being shown. To interpret the types of pets that the children chose, you read the very top of the bar to see which number it reaches on the y axis.
Do the ends of the line graph have to join?
The ends of the line graph do not have to join to the axes. You can tell at a glance that the temperature was at its highest on Monday and that it started to fall in the middle of the week before rising again at the end of the week.
