Answer:
- B
- B
- a) f(3y-1) = 24y -17; b) f(-7/4) = -23
Step-by-step explanation:
1. Any mapping requiring segment lengths to be congruent will require a "rigid" transformation, some combination of rotation, reflection, and translation.
If the transformation is not one of those, then segment lengths may change. The transformation we usually study that is not a rigid transformation is <em>dilation</em>. It preserves angles and slopes, but not segment lengths.
Of the choices listed, only choice B does not involve congruent segments.
__
2. In line with the discussion above, the dilation will preserve the slope of KM so that it is the same as the slope of K'M'. This is described by choice B.

3.
a) Finish simplifying the equation already written.
f(3y -1) = 8(3y -1) -9 = 24y -8 -9
f(3y -1) = 24y -17
b) f(x) = -23
8x -9 = -23
8x = -14 . . . . . . add 9
x = -14/8 = -7/4 . . . . divide by 8, reduce the fraction
x = -7/4 = -1.75
