Step-by-step explanation:
the slope is always the factor of x (a) in the line equation.
either in
y = ax + b
or in
y - y1 = a(x - x1) with (x1, y1) being a point on the line.
it represents the ratio of "y coordinate change / x coordinate change" when going from one point on the line to another.
and so, the slopes of the 2 lines are
1/2
2
