b. vertical stretch by factor 3, reflection across the x-axis, then a
vertical shift up 1 unit
c. reflection across the y-axis, vertical shift up by 1 unit, horizontal
shift right by 3 units
o
d. horizontal compression by factor 3, vertical shift by 1 unit up, then
a reflection across the x-axis

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.
