What are the two lines on a graph?
The line graph comprises of two axes known as ‘x’ axis and ‘y’ axis. The horizontal axis is known as the x-axis. The vertical axis is known as the y-axis.
How do you know if a graph has two lines?
How Do I Find the Point of Intersection of Two Lines?
- Get the two equations for the lines into slope-intercept form.
- Set the two equations for y equal to each other.
- Solve for x.
- Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.
How do you describe a 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 do you notice about parallel lines?
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.
What is it called when two lines are on top of each other on a graph?
The lines which coincide or lie on top of each other are called coincident lines. They could be oblique lines or intersecting lines, which intersect at different angles, instead of perpendicular to each other.
What happens when two lines intersect?
The intersecting lines (two or more) meet only at one point always. Two intersecting lines form a pair of vertical angles. The vertical angles are opposite angles with a common vertex (which is the point of intersection).
What is the intersection of two lines in geometry?
In geometry, an intersection is a point, line, or curve common to two or more objects (such as lines, curves, planes, and surfaces). The simplest case in Euclidean geometry is the intersection of two distinct lines, which either is one point or does not exist if the lines are parallel.
How do you describe a graph?
Data can be represented in many ways. The 4 main types of graphs are a bar graph or bar chart, line graph, pie chart, and diagram. Bar graphs are used to show relationships between different data series that are independent of each other. Line graphs represent how data has changed over time.
How do you summarize a graph?
Use precise vocabulary like steadily declined and a sharp increase to describe trends. Use linking expressions like while and in contrast to make comparisons. The question asks you only to ‘Summarise the information’. Don’t give reasons why these trends might have occurred, or your personal preferences on the topic.
What does it mean for 2 lines to be parallel?
Parallel Lines: Definition: We say that two lines (on the same plane) are parallel to each other if they never intersect each other, ragardless of how far they are extended on either side. A transversal of two (or more) lines is another line that intersects the two lines.
