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.
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.
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.
How do you determine velocity using a position-time graph?
You can't determine velocity from that graph, because the graph tells you nothing about the direction of the motion. But you can determine the speed. The speed at any moment is the slope of a line that's tangent to the graph at that moment.
How do you know when a graph is proportional?
It makes a line ,it goes through the origin, it has a constant
How can you use a bar graph to determine which state had the least number of votes?
Find the shortest bar and read what state it represents. (In a bar graph, the length of each bar is proportional to the number it represents. )
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.
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.
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.
How can you tell from the graph of Molly's garden on the previous slide that it represents a proportional relationship?
The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
Is it true that the graph of a proportional relationship does not include the origin?
It is true in the case of inversely proportional relationship.

Plot a of graph period T s against length l cm?
the graph is directly proportional
What is a proportional graph line?
It is a straight line through the origin.
Does a graph with a proportional relationship always intersect at the origin?
Yes.
