一次函数是一种重要的函数,在现实生活中有着广泛应用。例1两摞相同规格的饭碗整齐地叠放在桌面上,请根据图1中给出的数据信息解答问题: (1)求整齐叠放在桌面上饭碗的高度y(cm)与饭碗数x(只)之间的一次函数解析式(不要求写出自变量x的取值范围); (2)若桌面上有12只饭碗,整齐叠放成一摞,求出它的高度。 A function is an important function and has a wide range of applications in real life. Example 1 The two rice bowls with the same specifications are stacked neatly on the tabletop. Please answer the questions according to the data information given in Figure 1. (1) Find the height y (cm) and the number of rice bowls that are neatly stacked on the desktop. x (Only) a one-function analytical formula (without writing the range of values ​​of the independent variable x); (2) If there are 12 rice bowls on the table, stack them neatly into one stack, and find the height of it.
