Do dialations always increase the length of line segments

While they scale distances between points, dilations do not change angles. ... Transformations affect all points in the plane, not just the particular figures we choose to analyze when working with transformations. All lengths of line segments in the plane are scaled by the same factor when we apply a dilation

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.

20000 as first it increases by 2500 then by 5000 so next it will increase by 10000
