For a $2$D dataset analyzed with PCA, if the eigenvector for the first

principal component $($PC$1)$ is $(0\mathrm{.}77,0\mathrm{.}64)$ and you have two data points

$A=(2,-1)$ and $B=(-3,4),$ which of the following statements is true

regarding their projections onto $PC1?$

Both project equally onto the eigenvector

A projects further onto the eigenvector

than B

$B$ projects further onto the eigenvector than $A$

It's impossible to determine without calculating the projections.
