m mean slope in parallel lines and it is always same in two parallel lines.
Given:
Linear equations are generally described by the slope-intercept
represented by the equation y = mx+b
where m = slope
b = y-intercept.
In parallel lines:
Slope is always same means that two parallel lines have same slopes because those are not intersect at any point.
Example:
y = 3x + 4
here slope m = 3
The parallel line to this equation is also have the same slope.
