## What is it called when a line graph goes up?

So far, all of the graphs discussed have had a line that either always goes up or always goes down (the technical term for this is monotonic). Other relationships are more complex, with lines than can go up and down (called non-monotonic).

### How do you know if a graph line is going up or down?

That means down is the negative direction for rise. A way to remember this is to think about the numbers are on the y-axis. Going up above the origin are the positive values, and going down below the origin are the negative values.

#### What does it mean when the graph goes up?

In plain English, as you look at the graph, from left to right, the graph goes up-hill. The graph has a positive slope. By definition: A function is strictly increasing on an interval, if when x1 < x2, then f (x1) < f (x2).

**What do you call a up and down graph?**

A line graph plots data in a single line over time. To describe the graph, follow it’s progress along the horizontal access and describe whether it goes down, up, or stays the same.

**What is the trend of the graph?**

A trend line (also called the line of best fit) is a line we add to a graph to show the general direction in which points seem to be going. Think of a “trend” as a pattern in math. The trend line is something we add to our graph to make the pattern even clearer.

## How does rise over run work?

All you need to do is calculate the difference between the two points in the vertical direction (rise) and then divide it by the difference in the horizontal direction (run).

### What is the trend of a graph?

A trend is a pattern in a set of results displayed in a graph.

#### What is a best fit line graph?

Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software.

**How do you create a line graph?**

Viral star Mark Hoyle and his wife Roxanne have made history as LadBaby has clinched their fourth Christmas number one in a row, the first act ever to do so, and beating rivals The Kunts to the festive top spot after a bitter chart battle.

**How to make a line graph?**

Start with the data. Have your X- and Y-axis data ready.

## How do you read a line graph?

Identify what the graph represents. Most graphs will have a clearly labeled x-element,spaced along the graph’s horizontal axis,and a clearly labeled y-element,spaced along the graph’s vertical
