When a line is going up, it means it has a positive correlation

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".

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.

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.

that When our X-value increases, our Y-value is also increasing

This means that as x increases, the y is also increasing. So it is a positive slope meaning an increase

If the line is going up that's mean it's slope (gradient) is positive and the function is increasing in this interval.

A graph just shows the values of a function depending on what x value you put into it. If the graph is going up, then this means that as you increase the value of x that you put into the function, the value of the function also always increases :)

Click here to view my profile and arrange a free introduction.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.
