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

It is positive slope which means that as the input (x-axis) increases so does the output (y-axis). In other words when x is bigger than y has to get bigger.

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 means the slope is positive

Hi Antonietta,

that means the line of the graph has a positive gradient. Therefore, as the value for x increases the value of y also increases!

When a line on a graph is going up, it means that there is a positive gradient

It has a positive gradient

This would show a positive correlation as one value increases so does the other.

If this is a straight line graph, it means that it has a positive gradient. Another way of saying that is that whenever you make x bigger, y has to get bigger too.

If we're talking about scatter graphs, and this is a line of best fit, it means there is a positive correlation between the variables, so if one is high the other is likely to be high too, and when the first is low the second is likely to be low too.

The answer can change depending on the context of the graph (ie: the labels on the x-axis and y-axis). Generally, when a line on the graph is going upwards, it is said to have a positive gradient.

This means that on any point of the line, it should be the case that the y-coordinate divided by the x-coordinate will give a positive answer. As an inequality it would be "(y/x) > 0".

This means that there is a positive correlation. So, as one thing increases, so does the other. Sort of like the more air you blow into a balloon, the bigger it gets!

When the line in graph goes vertical up its slope is undefined.

Positive gradient, so as one variable increases, so does the other.

This shows a potential relationship between the 2 variables. This is known as a correlation. Upwards = positive.

(Assuming it’s a straight line going from bottom left to top right) it means that the line has a positive gradient and shows that there’s a positive relationship between the 2 variables
