A graph has two axes, the one running top to bottom (vertical or y axis) and one running right to left (horizontal or x axis). You can run your finger up the y axis to the point where it is at the same height as the point on the line you are interested in, and note the number on the y axis, then run your finger across to the point on the line you are interested in, then take your finger down to the x axis and note the number of that axis, then combine the two.
For example, if the graph shows height on the y axis and time on the x axis, you go up the y axis to say, 23 cm, then across to the point on the line, then down to the x axis which is say, 12 hours, then you know that by 12 hours the plant (for example) had grown 23 cm.

If the bubble is up its a good thing... down baaad
title, key etc.
Each point on a line graph in 2-dimensional space can correspond to an ordered pair of values for two variables which is observed. Or, if it is a fitted line graph, it is an estimated ordered pair.
A line graph is good cause it is easier to read
It is easier to read because it can be not as cluttered as a bar graph or scatter plot graph.
Yes
look and see
No titles or axis' No numbers Or making the graph difficult to read
:Troll:
yes
The answer depends on what the graph is meant to show. The first step would be to read the axis labels.
Because when you graph a molar concentration vs. absorbance graph, the graph is linear, making the graph easier to read.

Distance you read off directly from the graph. Speed is the rate of increase of distance, so it is the slope (gradient) of the graph.
