Answer:
C = (1, -1)
Step-by-step explanation:
For that 3:1 division, the calculated value of point B is ...
B = (3C +1A)/(3+1)
Solving for the value of C, we find ...
4B = 3C + A . . . . multiply by 4
4B -A = 3C . . . . . subtract A; next divide by 3.
C = (4B -A)/3 = ((4(-1)-(-7))/3, (4(0)+-3)/3) . . . . substitute given values
C = (3/3, -3/3) . . . . simplify a bit
C = (1, -1)
