Step-by-step explanation:
Moving the line left would be moving it onto the y - axis
Therefore the solution would be any point that starts with 0
So (0, 1), (0, 2), (0, -9), etc.
We know,
1 unit : 5 feet
so, 120 ft = (120 / 5) units
= 24 units
75 ft = (75 / 5) units
= 15 units
∴ Dimensions of scale drawing is 24 units by 15 units.
