# vec(r) = ( (-1), (4) ) + lamda ( (6), (-10) )#

#### Explanation:

The vector equation of a line in the direction of

# vec(r) = vec(A) + lamda vec(D) #

So the required equation in vector form is:

# vec(r) = ( (-1), (4) ) + lamda ( (6), (-10) )#

Alternative notations are:

# vec(r) = <<-1, 4>> + lamda <<6,-10>> #

Or,

# vec(r) = (-1hat(i)+4hat(j)) + lamda (6hat(i)-10hat(j)) #
