You can write a proportionality (between "x" and "y") as:
y = kx
where x is some constant.
For x = 0, y is also equal to zero, no matter what the value of k. Thus, the point (0, 0) - i.e., the origin - is part of the solution set.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
Yes.
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
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.
Oh, what a lovely question! To create a graph of a proportional relationship, you'll need two important components: the x and y axes. The x-axis represents the independent variable, like time or distance, while the y-axis represents the dependent variable, such as speed or cost. By plotting points where the values are directly proportional, you can connect them with a straight line that passes through the origin. Happy graphing!
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
It can be either a straight line through the origin or a hyperbola.
A graph shows a proportional relationship if it is a straight line that passes through the origin (0,0). This indicates that as one variable increases, the other variable increases at a constant rate. Additionally, the ratio of the two variables remains constant throughout the graph. If the line is not straight or does not pass through the origin, the relationship is not proportional.
It is true in the case of inversely proportional relationship.
Yes.
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.
It's a slanted straight line that goes through the origin of the coordinates.
A straight line through the origin, and with a positive gradient (sloping from bottom left to top right).
The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
If a proportional relationship is graphed on the coordinate plane, what things must be true?
