proportional relationships occur when two quantities increase or decrease at the same ______. the graph of a proportional relationship is always a straight line that passes through the ______. the slope of a line in a proportional relationship represents the ______ of change. in a table representing a proportional relationship, each row shows a pair of values that follow the same constant ______. the general form of the equation for a proportional relationship is ______ = kx. when creating a graph, the x - axis typically represents the ______ variable.

Question

Accepted Answer

### 1st Blank:
# Brief Explanations:
Proportional relationships involve two quantities changing at a consistent rate (same ratio). So the word here is "rate".
# Answer:
rate

### 2nd Blank:
# Brief Explanations:
The graph of a proportional relationship ($y = kx$) is a straight line passing through the origin $(0,0)$ since when $x = 0$, $y=0$.
# Answer:
origin

### 3rd Blank:
# Brief Explanations:
In a proportional relationship $y=kx$, the slope $k$ is the constant rate of change (how much $y$ changes per unit $x$ change).
# Answer:
constant rate

### 4th Blank:
# Brief Explanations:
In a proportional relationship table, the ratio $\frac{y}{x}$ (or $\frac{x}{y}$ depending on definition) is constant (the constant of proportionality). So the pair of values follow the same constant "ratio" (or "proportionality").
# Answer:
ratio (or proportionality)

### 5th Blank:
# Brief Explanations:
The general equation for a proportional relationship is $y=kx$, where $y$ is the dependent variable and $x$ is independent. So the blank is $y$.
# Answer:
$y$

### 6th Blank:
# Brief Explanations:
In graphs, the $x$-axis typically represents the independent variable (the one we can control or that changes freely), and $y$ is dependent on $x$.
# Answer:
independent
