On the xy-coordinate plane, what is the area of a right triangle, one side of which is defined by the points (2,3) and (-4,0)?

(1) The triangle's sides cross the y-axis at exactly two points altogether.

(2) The y-coordinate of the third vertex of the triangle is zero

请问（1）是什么意思？麻烦哪位翻译一下中文。谢了。

三角形的边共有两点通过Y轴

答案是C么?

我的答案是E

直角边有两种可能。
