Answer:
the slope is flatter.
the line is shifted down by 13 units (or shifted by -13 units).
Explanation:
the slope of a line is expressed by the ratio y/x defining how many units y changes, when x changes a certain amount of units.
the slope of A is 2 (factor of x) = 2/1.
and that means when x changes one unit, y changes 2 units.
the slope of B is 1 = 1/1.
when x changes 1 unit, y changes 1 unit. so, B is flatter (it does not climb up so fast).
and the constant numbers in the equations give us the offset of the lines in y direction for x=0.
A cuts the y-axis at y=+4, and B cuts it at y=-9.
so, B is shifted from A by 4 - (-9) = 13 units.
