The coordinates of the top of a tree are -3,8 , and an acorn is attached to the tree at -1,5 If we know that the acorn lies exactly halfway between a squirrel and the top of the tree, what are the coordinates of the squirrel?
answer please!
Thanx!!!!!!!!!!!!!!!!!!!!!!

Hello Guest!
\(P_1(-3,8)\\ P_2(-1,5)\\ m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-8}{-1-(-3)}\\ \color{blue}m=-1.5\)
\(y=m(x-x_1)+y_1\\ y=-1.5(x-(-3))+8=-1.5x-4.5+8\\ \color{blue}y=-1.5\cdot x+3.5\\ y_3=y_2-(y_1-y_2)\\ y_3=5-(8-5)\\ \color{blue}y_3=2\)
\(y_3=-1.5\cdot x_3+3.5\\x_3=\frac{y_3-3.5}{-1.5}=\frac{2-3.5}{-1.5}\\ \color{blue}x_3=1\\ \color{blue}The\ coordinates\ of\ the\ squirrel\ are\ 1,2.\)
