Find an equation of variation in which y varies inversely as the square of x and y = 24 when x = 4. ( So, Joint variation. If a situation gives rise to a linear function , where k is a constant, we have joint variation. The number k is called the constant of proportionality. Key phrase identifying joint variation: y varies jointly as x and z ...
