Why should you not expect all data points to fall on the straight line representing the data even if the properties being studied are directly proportional to each other?

Why is the graph between load and deflection a straight line?
Because load and deflection are directly proportional to each other
What are the properties of proportional and non-proportional tables and graphs?
If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.
Is this equation directly proportional y equal m times x plus b where b is a non zero number?
No. Although this an equation of a straight line and y increases when x increases, a directly proportional equation has y/x = constant. So if b is zero it is in direct proportion, but not if b is non zero
What is an equation for s directly proportional relationship that starts with y?
It is a straight line equation in the form of: y = mx+b whereas 'm' is the slope and 'b' is the y intercept
What is the definition of proportional relationships in graphs?
Either a straight line through the origin or a hyperbola.
What is the graph of two variables that are directly proportional to one another is?
a straight line

What is the result when AC flows through a straight wire?
power loss will be more in heating of the wire.powertransit is directly proportional to thesquirof the circumference.
Y is directly proportional to x?
If a variable (such as y) is directly proportional to another variable (such as x), they both increase and decrease simultaneously. An equation for two directly proportional variables is:y = axIt's sort of like a linear equation, but it always goes through the origin.An example is y = 6x. Notice that it forms a straight line and crosses the origin, and that y and x increase in the same direction.
What is graphing proportions?
Graphing proportions is to take two ratios and plot them on an (x,y) coordinate plane. You need to be consistent with your labeling. If you use the numerator of one ratio as your x coordinate, then the numerator of the other ratio must be the 2nd x coordinate. You can graph as many of these points as are given. If your ratio's are proportional then you will have a straight line. If it is not a straight line when graphed your ratios are not proportional.
Is this equation directly proportional y equal m times x plus b where b is a non zero number?
No. Although this an equation of a straight line and y increases when x increases, a directly proportional equation has y/x = constant. So if b is zero it is in direct proportion, but not if b is non zero

What is a proportional graph line?
It is a straight line through the origin.
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.
How do you know if a graph is proportional?
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
What does directly porportional mean?
It is a special kind of linear function wear the line on a graph goes straight through the origin. If x is directly proportional to y, then it means that for a value of x, y = cx, where c is some constant. For example, if a slice of pizza costs a fixed cost (say 1 dollar), then the cost of your pizza meal is directly proportional to the number of slices you order. (Cost = 1 times number of slices.)
