the x-intercept =—b/a,the y-intercept=b
--b/a=2b
so a=--1/2
the slope of the line=a=--1/2

这是网友给的答案和解题的图片.求问切线AB的斜率怎么算?数字是怎么出来的?

过圆X²+ Y²= 1的切点P(3/5,4 / 5)的切线AB在Y轴上的截距为OB,求OB,
法线OP的斜率k=(4/5)/(3/5)=4/3,切线AB的斜率k1=-1/(4/3)=-3/4,
AB的切线方程,按点斜式有:y-4/5=(-3/4)(x-3/5)=(-3/4)x+9/20
y=(-3/4)x+5/4,x=0时,y=5/4,
切线AB在Y轴上的截距为5/4.



完整题目What is they-intercept of the line tangent to the circle x²+y²=1 at the point (3/5,4/5)?

就是那样算没错 相互垂直的两条直线斜率相乘的值为-1 知道这个了 再求出OP斜率 自然知道AB斜率

求3x+4y=24的y轴截距是多少?
应是当x=0时,求y;所以y=6

截距是值
对于直线来说,截距一般指的是直线与y轴交点的纵坐标的值

(a)证明A到C的距离等于B到D的距离.(两点间的距离好算吧?)
(b)求经过A点和C点的斜率截距方程,y=f(x).(已知两点求直线方程)
(c)求经过B和D的直线方程,y=g(x).
(d)总结并解释f(x)与g(x)之间的几何关系.(就是类似于相交啊,平行啊之类的)
(e)求f(x)和g(x)的交点坐标P.
(f)P是不是由A、C连成的线段的中点.
(g)P是不是由B、D连成的线段的中点.
(h)画出f(x),g(x)的草图,要求包含题中给出的所有点和坐标轴中的信息.(这个我也没看太明白,大概就是说问题中给出的所有的点你都要描出来,并且在坐标轴上要有标记)

1、-11/7×-3-19/7
=33/7-19/7
=14/7
=2
(4,9), it can pass through the equation.
remain the given points can not be pass thorough the equation.
