Answer: y = - x - 6
Step-by-step explanation:
The line crosses the y intercept at y = -6
The slope of the graph looks negative, as it extends from the top left quadrant to the bottom right quadrant.
A key trick is to use rise/run to figure out the slope:
Between each dot on the line, it rises 2 and runs -3 (negative because the direction is left).
So your equation would be: y = - x - 6
Given:
The figure of a triangle LMN.
P is the centroid of triangle LMN.
To find:
14. Find the value of PN if QN=30.
15. Find the value of PN if QN=9.
Solution:
We know that the centroid in the intersection of medians of a triangle and centroid divides each median in 2:1.
Since P is the centroid it means NQ is the median from vertex N. It means P divides the median NQ in 2:1. So, PN:PQ=2:1.
14. We have QN=30.
Therefore, the value of PN is 20 when QN=30.
15. We have QN=9.
Therefore, the value of PN is 6 when QN=9.
