Week 14–Math 10

This week I solve a difficult question.

Here is the question.


This question is about midpoint, the midpoint formula is:


The question also tells us the slope is -3, means m=-3/1, and the slope formula is m=(y2-y1)÷(x2-x1), so we could use the point (1,6) to figure our the other point. The question said “The other endpoint is on the x-axis” it means the other point must be (x,0). According those information above, we could have a equation:


Then we got the other endpoint is (3,0). Now we just use the midpoint formula before, FullSizeRender

This is the final answer.
