看不懂英文啊 T T
state whether or not each equation defines a direct variation .for each direct variation ,state the constant of variation.
1,y=3x 2,p=4/q (这些只给一个数,看不懂……)
---------
state whether or not formula shows a direct variation
1,x1/y1=x2/y2 2,x1/x2=y1/y2
3,y1/x2=y2/x1 4,y2/x2=y1/x1
--------
x1=15 ,y1=9
x2=40,y2=?

1、一个问题是在问你哪个方程是正比例函数.第二个问题是要你把比例常数描述一下.1)y=3x是正比例函数.2)y=3x的比例系数是3,p=4/q的比例系数是4
2、问你下列方程是不是正比例函数.第三个不是.
x1/x2=y1/y2
y2=y1/(x1/x2)=3*8=24
2、问你下列方程是不是正比例函数.第三个不是.
x1/x2=y1/y2
y2=y1/(x1/x2)=3*8=24
