does the graph show a proportional relationship if so what is the constant proportionality and what does it represent |
|
Answer» To determine whether x and y have a proportional relationship, see if the line through these points PASSES through the origin (0, 0). The points are on a line that passes through the origin. So, x and y have a proportional relationship.Proportional RELATIONSHIPS are relationships between two variables where their ratios are EQUIVALENT. Another way to think about them is that, in a proportional relationship, one VARIABLE is always a constant VALUE times the other. That constant is know as the "constant of proportionality". |
