Direct proportions may be represented by a straight line through the origin, with the equation y = kx. The gradient of the line is the constant of proportionality and is a measure of the change in the "dependent" variable for a unit change in the "independent" variable. In the case of an inverse proportionality, the graph is a hyperbola with the equation y = k/x. The constant of proportionality, k, is a measure of the change in the reciprocal of the "dependent" variable for a unit change in the "independent" variable.
What else can I help you with?
Which are the characteristics of proportional relationship graph?
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
What does the graph of a proportional relationships look like?
A straight line with a positive slope, passing through the origin.
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.
Are speed and distance directly proportional or inversely proportional?
Directly proportional. Greater speed - greater distance.
If two quantities are (proportional nonproportional) they have a constant ratio.?
The answer is proportional.
What is true about ratios for proportional relationships that is not true about ratios for other relationships?
For proportional relationships the ratio is a constant.
How are proportional and non proportional relationships alike?
Proportional and non-proportional relationships both describe how two variables interact and change in relation to one another. In both types of relationships, changes in one variable can affect the other, and they can be represented graphically, typically with a line. However, while proportional relationships maintain a constant ratio between the variables, non-proportional relationships do not, leading to different patterns in their graphs. Both are essential for understanding mathematical concepts and real-world applications.
Do linear graphs represent proportional relationships?

How are proportional and non proportional relationships similar?
They aren't.
What does proportional relationships mean?

How are proportional and non proportional linear relationships different?
Proportional linear relationships have a constant ratio between the two variables and pass through the origin (0,0), meaning that if one variable is zero, the other is also zero. In contrast, non-proportional linear relationships do not have a constant ratio and do not necessarily pass through the origin; they include a y-intercept that is not zero, indicating a fixed value when the independent variable is zero. This results in different graphs, with proportional relationships forming straight lines through the origin and non-proportional relationships forming straight lines that intersect the y-axis at a point other than the origin.

What are proportional relationships in graphs?
Proportional relationships in graphs are represented by straight lines that pass through the origin (0,0). In these relationships, the ratio of the two quantities remains constant, meaning that as one quantity increases or decreases, the other does so in a consistent manner. This can be visually identified by the slope of the line, which represents the constant ratio. Overall, proportional relationships illustrate a direct correlation between two variables.
