$(x,y,z) = (4,1,-3)+n(1,2,3)$

Work Step by Step

In general we can write an equation for a line in this form: $(x,y,z) = (a,b,c)+n(a',b',c')$ where $(a,b,c)$ is a point on the line and $(a',b',c')$ is a direction vector $(4,1,-3)$ is a point on the line $(1,2,3)$ is a direction vector We can write an equation for this line: $(x,y,z) = (4,1,-3)+n(1,2,3)$
