愣是题目都没怎么理解,请各位帮我翻译一下,再分析一下,谢谢!!!
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 triagle's sides cross the y-axis at exactly two points altogether
2) the y-coordinate of the third vertex of the triangle is zero
谢谢各位,心里很着急! |
