A dilation maps point Q(1, 2) to its image Q(2, 4). The completed figure Q'R'ST' is on the graph. What is the scale factor? Enter your answer in the box

two data sets with the same median will not have the same varaibility

step-by-step explanation:

25% is the answer

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

3
