外国数学问题,请大家帮忙解决.
-solving line equation
y=6(-8-x)-6,
-2(x+2)=-2+2y
-calculating slope and y-intercept
4+x=4(y+3)
-6(y-2)=-24-x
find a perpendicular a line containing a given point
4(x+4)=2x-y (-4,-4)
-3+y=-4(x+8) (-3,7)
find a parallel line containing a given point
7-y=8(1-2x) (-2,8)
2(y-5)=6-5x (-6,-3)
我还要写过程,中文我不懂怎么翻译.谢谢大家.
