m:n=3:5

We know


\boxed{\sf M(x,y)=\left((mx_2+nx_1)/(m+n),(my_2+ny_1)/(m+n)\right)}


\\ \sf\longmapsto M(x,y)=\left((3(7)+5(-1))/(3+5),(3(7)+5(1))/(3+5)\right)


\\ \sf\longmapsto M(x,y)=\left((21-5)/(8),(21+5)/(8)\right)


\\ \sf\longmapsto M(x,y)=\left((16)/(8),(26)/(8)\right)


\\ \sf\longmapsto M(x,y)=\left(2,(13)/(4)\right)

  • x_1=-1
  • x2=7
  • y1=1
  • y2=7
  • m:n=3:5

We know


\boxed{\sf P(x,y)=\left((mx_2+nx_1)/(m+n),(my_2+ny_1)/(m+n)\right)}


\\ \sf\longmapsto p(x,y)=\left((3(7)+5(-1))/(3+5),(3(7)+5(1))/(3+5)\right)


\\ \sf\longmapsto p(x,y)=\left((21-5)/(8),(21+5)/(8)\right)


\\ \sf\longmapsto p(x,y)=\left((16)/(8),(26)/(8)\right)


\\ \sf\longmapsto p(x,y)=\left(2,(13)/(4)\right)
