How do you graph greater than XY?
There are three steps:
- Rearrange the equation so “y” is on the left and everything else on the right.
- Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
- Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).
Is graphing X over Y?
The x-coordinate always comes first, followed by the y-coordinate. As you can see in the coordinate grid below, the ordered pairs (3,4) and (4,3) are two different points!
How do you describe the trend of a graph?
A trend is the overall idea of the graph • what is happening/what happened • the main change over time • the most noticeable thing about the graph • the pattern over time • the pattern for different places or groups or people. Most graphs will have two trends, or there will be two graphs with a trend in each.
How do you describe a fluctuating graph?
Small changes up and down are called ‘fluctuations’. We can describe this graph as follows: The revenues increase slightly over the first quarter (January to March) while there is a developing loss. Between March and April revenues increase significantly and there is a profit to correspond with this.
How do you write a system of inequalities from a graph?
When writing an inequality from a graph, there are a few things we need to do:
- Determine the equation of the line. This gives us the general form of our inequality once we remove the equal sign.
- Note whether the line is dotted or solid.
- Use the graph’s shading to determine which way your inequality sign will face.
How do you analyze graphs and charts?
To interpret a graph or chart, read the title, look at the key, read the labels. Then study the graph to understand what it shows. Read the title of the graph or chart. The title tells what information is being displayed.
How do you summarize an Ielts chart?
Use a range of vocabulary and do not make spelling mistakes.
- Use different verbs and nouns.
- Use a range of adjectives and adverbs.
- Vary your time phrases.

What do you call a graph that goes up and down?
Also known as a line chart, it can tilt towards the positive y-axis (go up), approach the negative y-axis (go down) or as depending on. That is, a line graph can ascend, descend, or do both depending on the kind of data that is being evaluated.
How do you explain a curved graph?
A straight line would indicate a constant rate of reaction, while a curve indicates a change in the rate (or speed) of a reaction over time. If a straight line or curve flattens into a horizontal line, that indicates no further change in the rate of the reaction from a certain level.
How do you find an inequality on a graph?
Plug your slope and a point into the formula y = mx + B, in which “m” is the slope, (x, y) is a point on the line and “b” is the y-intercept, to find the equation governing the inequality line. Plugging in (0, 0), you obtain 0 = 0 + b, so b = 0. Rewriting the equation, you obtain y = x/2.
How do you graph an inequality on a graph?
To graph an inequality, treat the <, ≤, >, or ≥ sign as an = sign, and graph the equation. If the inequality is < or >, graph the equation as a dotted line. If the inequality is ≤ or ≥, graph the equation as a solid line.
How do you graph x x and Y Y values?
Create a table of the x x and y y values. Graph the line using the slope and the y-intercept, or the points.
How to graph a line in the xy-axis?
Another excellent method to graph a line in the xy-axis or xy-plane is to use its intercepts. What are intercepts? These are points of the line that are found on the x and y axes. We have two kinds of intercepts.
How do you graph a line using X and y intercepts?
Graphing a Line using the x and y-Intercepts. The second is the y-intercept which is the point of the line located somewhere in the vertical axis (y-axis). Here is a quick diagram that gives you the idea. Since the x-intercept is a point where the line crosses the x-axis, it is a point with a y-value of zero.
What is the difference between x axis and y axis?
Together, they form a coordinate plane. The x-axis is usually the horizontal axis, while the y-axis is the vertical axis. They are represented by two number lines that intersect perpendicularly at the origin, located at (0, 0), as shown in the figure below.
