The end points of ab are a(2,2) and b(3,8). ab is dilated by a scale factor of 3.5 with the origin as the center of dilation to give image a1b1. what are the slope (m) and the length a1b1

Step-by-step explanation:

Dilation does not change the slope, so it remains ...

  m = ∆y/∆x = (8-2)/(3-2) = 6/1

  m = 6

The length is multiplied by the dilation factor. The original length (d) is given by ...

  d = √((∆x)^2 +(∆y)^2) = √(1^2 +6^2) = √37

Then the dilated length is ...

  3.5d = 3.5√37 ≈ 21.290
