What is proportional relationship in math terms?
Two variables are proportional to one another if there is a simple relationship, of the following form:The variables X and Y are indirect proportion if Y = c*Xandinverse proportion if Y = d/X or, equivalently, X*Y = dfor some non-zero constants c and d, called the constants of proportionality.Note that if Y is inversely proportional to X, then Y is directly proportional to the variable 1/XThe graph of a direct proportion is a straight line through the origin, with slope = constant of proportionality.
Does the graph represent a proportional or non-proportional liner relationship How do you know?
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
Are linear relationships proportional?
A relationship that occurs when variable quantities are directly proportional to one another. A linear relationship can be represented on a graph as a STRAIGHT LINE. Linear relationships always follow the formula: y=mx+b where y is the value of the y-coordinate, where my is the slope of the line, where x is the value of the x-coordinate, and b is the y-intercept
What is relationship among proportional relationships lines rates of change and slope?
The graph of a relationship in which two variables are in direct proportion is a straight line through the origin, whose slope = the rate of change = the constant of proportionality.
Does a graph with a proportional relationship always intersect at the origin?
Yes.
How can you tell the difference between a graph in which one variable is directly proportional to another and a graph in which two variables vary inversely?
1. You can tell the difference because the proportional one has the same slope while the inversely one has opposite reciprocal slope.
When a graph shows two variables are directly proportion the slope will be?
If the two variables are directly proportional, then the slope can be any number,but the y-intercept has to be zero ... the line must go through the origin.
What is directly and invertly related on a graph?
The x value and the y value are directly and invertly related on a graph. This only occurs in a specific type of graph called a proportional graph.
What are the two way to determine if the relationship between two quantities are proportional?
Graphical: If two variables are proportional, the graph of one of the variables against the other is a straight line through the origin.Algebraic: If the ratio of the two variables is a constant.
If a linear graph has a negative slope what can you say about the dependant variable?
You can say that the variables are inversely proportional.
Plot a of graph period T s against length l cm?
the graph is directly proportional
Do all linear equations need to be proportional?
No.A directly proportional graph has an equation of the form y = mx. It always passes through the origin.A linear graph will have an equation in the from y = mx + c. This has a y-intercept at (0, c). It doesn't pass through the origin unless c = 0. The directly proportional graph is a special case of a linear graph.

Why do inversely proportional functions have asymptotes?
Because the two variables cannot be zero voltage = current*resistance if we draw graph current against resistance we would see a exponential graph which means the two variables are inversely proportional but either cannot be zero because voltage is not equal to 0 n.j.p
When a graph of two variables is a straight line passing through the origin the variables are said to be to each other?
It means that they are directly proportional to each other. As one variable increases, the other variable increases/decreases at a constant rate. The constant rate is determined by the gradiant of the straight line.
What are the uses of study of graph in physics?
Mainly , studying graph makes things more clear. Like what all things are inversely proportional and what all are directly proportional.... and all that sort of things. Hope you are satisfied. :D
Why does the graph of length against period not pass through the origin?
If the question is about a pendulum, the answer is that it should. However, the square-root of the length is directly proportional to the length so that the relationship between the two variables is not linear but quadratic. If the graph is extrapolated accordingly, then it will. There may still be an element of measurement error which may prevent the graph from going exactly through the origin.
