What is the relationship between a vector and a multi-variable linear function?

I know that the following linear equation:



$$ax_1 + bx_2 + cx_3 = d$$



can be rewritten as:



$$big[a quad b quad c big] left[ begin{matrix}
x_1 \
x_2 \
x_3 \
end{matrix} right] = d$$



Can it be represented in any other form?



I.e. is there any other relationship between a linear function and a vector?
