Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.

When two amounts are matching when one or the other of each the two amounts increases or decreases.

they are equivalent

Do all linear graphs have proportional relationship

They are directly proportional.

If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.

Proportional is when it is proportional.

Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.

no a proportional relationship is y / x = 5

For each of the following relationships, graph the proportional relationship between the two quantities, write the equation representing the relationship, and describe how the unit rate, or slope is represented on the graph.

They are inversely proportional or relationship to each other.

You cannot represent a proportional relationship using an equation.

It is true in the case of inversely proportional relationship.

A proportional relationship is of the form y = kx where k is a constant. This can be rearranged to give: y = kx → k = y/x If the relationship in a table between to variables is a proportional one, then divide the elements of one column by the corresponding elements of the other column; if the result of each division is the same value, then the data is in a proportional relationship. If the data in the table is measured data, then the data is likely to be rounded, so the divisions also need to be rounded (to the appropriate degree).

If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
