Two quantities p and q are connected vby a linear relation of the form p =kq+c where c and k are constants

Answer 1

This linear relation means that p and q are directly related and that the values of p and q can be determined by multiplying q by a constant k and adding a constant c. The constant c represents the value of p when q is zero, and the constant k represents the rate at which p increases or decreases for each unit increase in q.
