Parallel lines will have the same slope.
so if one of the lines has a slope of 1.3, then its parallel line will also have a slope of 1.3
If we are scaling up the surface area by a factor of 10 means that the two dimensions of area are each being increased by 10 times the original size. Therefore, the surface area is increased by a factor of 10 x 10, or by a factor of 100.
