Equations of lines: Consider the vector equation of the line through the two points listed above. For each equation listed below, answer T if the equation represents the line, and F if it does not. Here is the list of questions:

$1.(x,y,z)=($:$-2,3,5$:$)+t(5,-8,-10)$

$2.(x,y,z)=($:$-2,3,5$:$)+t(3,-5,-5)$

$3.(x,y,z)=(3,-5,-5)+t(5,-8,-10)$

$4.(x,y,z)=(-2,3,5)+c(-5,+8,+10)$

$5.(x,y,z)=(3,-5,-5)+t(-2,3,5)$
