a. The constant of proportionality, denoted as "k", represents the ratio of y to x in a proportional relationship. It is a constant value that remains the same across different values of x and y.
b. To write an equation that represents a proportional relationship, we can use the formula "y = kx", where k is the constant of proportionality. This equation indicates that the value of y is directly proportional to the value of x, with k representing the ratio between them.
c. In a proportional relationship, the y-intercept is always zero. This means that when x is zero, the value of y will also be zero.
