Answer:
k = 2
Step-by-step explanation:
the dilation k is the scale factor. A scale factor in math is the ratio between corresponding measurements of an object and a representation of that object. To find the scale factor k, we will compare the original points with their transformation
Point R is at (-1,2), and R' is at (-2,4).
divide the ys: 4/2 =2
divide the xs: -2/-1 =2
therefore the scale factor is 2
