What else can I help you with?
To visually determine whether there is a relationship between two variables?
Scatter chart
What kinda chart is used to visually determine whether there is a relationship between two variables?
scatter chart
How can you decide whether a relationship is linear by studying the pattern in a graph?
The graph must be a straight line, and it must pass through the origin.
What is the Advantages of scatter diagram?
It allows a quick look at the data to establish whether or not there is any relationship between the variables and also an indication of the nature of the relationship: linear, quadratic, power etc.
How do you use a table of data to check whether the relationship between two variables is a direct variation?
if it passes through (0,0) then it is a direct variation
When a question asks you to state the relationship between the variables what does that mean?
When a question asks you to state the relationship between variables, it is requesting you to describe how the variables are related to each other. This could include whether they have a positive or negative correlation, whether one variable causes a change in the other, or if there is no relationship between the variables.
Is helpful in determining whether there is a relationship between two variables?
it depends on who you are

What are scientists looking for when studying a line graph?
They can be looking for the shape of the relationship between the variables (whether it is linear, quadratic, reciprocal), and the domain over which that relationship extends. They may be looking for peaks or troughs in the line, they may be looking for harmonics, or periodicity. The answer really depends on what is being studied.
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
Can a graph help you interpret data?
Yes. It can give insight as to whether there is a relationship between two variables, and if so, whether the relationship is direct or indirect; whether it is linear, polynomial, exponential, logarithmic; whether or not there are asysmptotic values; whether or not there is clustering; etc.

How can you decide whether a relationship is linear by studying the words used to describe a variable?
Words such as "proportional to" "increases as" "decreases as", usually give an indication of a linear relation. If there are words like "Square" "power" "inversely proportional" then most likely not linear.

How does graphing relationships help you determine whether the relationship is proportional or not?
If the points lie on a straight line through the origin, the two variables are in direct proportion.
