Answer:
(1.2, –4.7)
Step-by-step explanation:
Since in the question it is mentioned that on the plane of coordinate, a line is made from point A (7,-2) to point B(-8,-9)
Also, the ratio of A to B is 5:8
Based on this, the x and y coordinates at point C is
= (1.2, –4.7)
Hence, the x and y coordinates of point C is (1.2, –4.7)
Therefore the last option is correct
First of all, don't let "b" confuse you. Know that b = 5/6k = -10, so all you really have to solve for this problem is .
Before anything else, you have to isolate k. Do this my multiplying both sides by the reciprocal of 5/6.
The 6/5 and 5/6 cancel each other out, so we are left with

So k = -12.
Hope this helped. Good luck.
