Surface area is square units, so you would need to square the scale factor.
The length was tripled, which means it is a scale factor of 3
3^2 = 9
The surface area would increase by a factor of 9.
The answer is B.
The coordinates of the centroid are given by:
![\begin{gathered} C=(xc,yc) \\ xc=\frac{Ax+Bx+Cx}{3} \\ yc=\frac{Ay+By+Cy}{3} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20C%3D%28xc%2Cyc%29%20%5C%5C%20xc%3D%5Cfrac%7BAx%2BBx%2BCx%7D%7B3%7D%20%5C%5C%20yc%3D%5Cfrac%7BAy%2BBy%2BCy%7D%7B3%7D%20%5Cend%7Bgathered%7D)
Therefore:
![\begin{gathered} xc=\frac{4+2+8}{3}=\frac{14}{3} \\ yc=\frac{8+0-4}{3}=\frac{4}{3} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20xc%3D%5Cfrac%7B4%2B2%2B8%7D%7B3%7D%3D%5Cfrac%7B14%7D%7B3%7D%20%5C%5C%20yc%3D%5Cfrac%7B8%2B0-4%7D%7B3%7D%3D%5Cfrac%7B4%7D%7B3%7D%20%5Cend%7Bgathered%7D)
The coordinates of the centroid are:
Answer:
-1/2
Step-by-step explanation:
When the equation of a line is given in the form y = mx + b like this is, the slope is simply the m value!
