IS和LM中利率与收入的关系怎么是相反的？

您好，这是我从宏观书上看的，初学者理解不深，我觉得应该是货币供求影响利率，利率反过来也保证了货币供 ...

你教教我怎么上图，我最近正好会看《通论》，给你把利率部分上传下，哈哈哈哈

哈哈哈，话说我也找了好久才知道怎么上图，您回复的时候点右边的“高级模式“，然后在新的回复界面里点加载图片的图标，再点普通上传，就可以选浏览，然后在电脑里选要上传的图，就可以上传了，谢了大神，还想着小弟的问题，感动ing

书上课后题有解释
The LM curve summarizes the relationship between the level of income and the inter- est rate that arises from equilibrium in the market for real money balances. It tells us the interest rate that equilibrates the money market for any given level of income. The theory of liquidity preference explains why the LM curve slopes upward. This theory assumes that the demand for real money balances L(r, Y) depends negatively on the interest rate (because the interest rate is the opportunity cost of holding money) and positively on the level of income. The price level is fixed in the short run, so the Fed determines the fixed supply of real money balances M/P. As illustrated in Figure 10–5(A), the interest rate equilibrates the supply and demand for real money balances for a given level of income.

Now consider what happens to the interest rate when the level of income increas- es from Y1 to Y2. The increase in income shifts the money demand curve upward. At the old interest rate r1, the demand for real money balances now exceeds the supply. The interest rate must rise to equilibrate supply and demand. Therefore, as shown in Figure 10–5(B), a higher level of income leads to a higher interest rate: The LM curve slopes upward.

我随手一百度

很简单，利率越高你得的利息就越多收入越高，所以货币收入曲线向上倾斜。

所以答案是啥呀 都没看懂呀
