When a line on a graph is going up, what does that mean?

It means it has a positive gradient

By a line going up on a graph, if your referring to correlations, then a line in the diagonal upwards direction would mean a positive correlation.

This reflects a positive gradient, for example on a distance -time graph this would mean increasing velocity, or on a velocity -time graph, increasing acceleration.

Hi, if a line on a graph is going up from left to right, it means there is a positive correlation between the factors of the x-axis and y-axis. In simpler terms, as the value on the x-axis increase so does the value on the y-axis.

It depends on the context. If you have a scattergraph with a line of best fit that rises from left to right it means the two variables have a positive correlation, so as one variable increases so does the other one. Note that because two variables are correlated it doesn't mean one causes the other to happen, there may be a missing unknown cause that links with the two others.

If the line is plotted from an equation and is diagonal, then it will mean that the gradient of the line is positive.

If the line is vertical then this is an "x" equation line, such as x = 2, where all of the x coordinates are that value.

That means it is sloping upwards assuming you are moving from left to right on the graph and the line is going up. Slope of a line is defined as it's rise over run. Rise being change in y-coordinates and run being change in x-coordinates.

Positive gradient or positive correlation

when a line is going up, it means the gradient is positive so the 'm' in y=mx+c is positive.

It means that as the x value is increasing, so does the y value. The linear relationship has a positive gradient, an increasing trend.

If a line is going up from left to right, it means that the gradient is positive. Straight line graphs have the form y=mx+c so this means that m will be a positive number.

positive correlation

If this line is straight going up, this means there is a positive linear correlation. As x increases, y increases.

It has a positive gradient

When the line on the graph is going up it means that there is a direct relationship between x and y, the two pieces of data that is being plotted. As x goes up y goes up also. We call this the gradient of the line. If it is going up there is a positive relationship between x and y.
