Line segment ab has vertices a(−3, 4) and b(1, −2) . a dilation, centered at the origin, is applied to ab . the image has vertices a′(−1, 43) and b′(13, −23) .

what is the scale factor of the dilation?

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
