Find the (x,y) coordinate

Question

For these problems you need to follow these steps. 

1. Find the Midpoint for each side of the triangle
2. Connect the Midpoints with two of the Medians
3. Determine the slope intercept form of two of the Median lines
4. Set the equations of the lines equal to each other to solve for the x point of intersection
5. Put the x back into one of the line equations you found to solve for the y point of intersection. This is the (x,y) point of the Centroid.

3. Find the (x,y) coordinate of the Centroid.

Answer 1

Side "a" midpoint=1,3

b =-5,0

c =-2,-9

Slope=rise/run.

Slope side "a"=18.-6
