Given a straight line y = - kx-2, P (- 2,1) Q (3,2) - when k = 2, what is the ratio of the intersection of the straight line and the line PQ to the partial vector PQ? Secondly, when there is an intersection between the straight line and the line PQ, what is the value range of K?
① Intersection R (- 17 / 11,12 / 11) PR / RQ = 1 / 10
② The intersection R (x, y), y = (7k-2) / (5K + 1). 1 ≤ y ≤ 2. The solution is k ≥ 3 / 2, or K ≤ - 4 / 3
[just give the answer, please add the details by yourself, OK?]
Given p (- 2,3), PQ is parallel to y axis
And PQ = 8, calculate the coordinates of Q point
There are two points (- 2,11) (- 2, - 5)
Point (2, - 1) is in the second position__ Quadrant, 3 units to the left__ And then the coordinate of 5 units up is__ At this time, the change point is in the second position__ Quadrant?
4、 (- 1, - 1), (- 1,4), two
If the point (- 2,3) is first shifted 3 units to the right and 2 units to the down, the coordinates of the point obtained are?
Add x to the right, and that's - 2 + 3 = 1
If you subtract y down, you get 3-2 = 1
So it is marked as: (1,1)
