For this case we have the following expression:
We clear the value of the variable "g", for this:
We multiply by 4 on both sides of the equation:
We divide by 3 on both sides of the equation:
We simplify:
Answer:
Step-by-step explanation:
Collinear points have the same gradient
find the gradient(slope) between AB first
Find the one for BC
Find the gradient between AC now
YOUR LAST STATEMENT NOW WILL BE
POINTS A,B AND C ARE COLLINEAR SINCE THE GRADIENTS BETWEEN THEM IS THE SAME!!!
