This question relates to the characteristics of handwriting.
Step 1: Define the terms.
(1) Baseline: The real or imaginary line upon which the letters rest.
(2) & (3) Alignment: Refers to the arrangement of letters and words in relation to the baseline. For example, the writing may follow the baseline, or trend upwards or downwards.
(4) Slant: Refers to the angle of the writing. It is the inclination of the axes of the letters relative to the perpendicular of the baseline. It can be forward (right-slanted), backward (left-slanted), or vertical.
Conclusion: The definition given in the question perfectly matches the definition of Slant.
