Guided Practice

  • Question 1 (request help)

     The grid shows a diamond-shaped preimage. Write the coordinates of the vertices of the preimage in the first column of the table.  Then apply the dilation (x, y) →\( ( \large\frac{3}{2}x, \frac{3}{2}y )\) and write the coordinates of the vertices of the image in the second column. Sketch the image of the figure after the dilation.
  • Type below:

Graph the image of each figure after a dilation with the origin as its center and the given scale factor. Then write an algebraic rule to describe the dilation.

  • Question 3 (request help)

    scale factor of \(\large\frac{1}{3}\)
  • Type below:

ESSENTIAL QUESTION CHECK-IN

  • Question 4 (request help)

    A dilation of (x, y) → (kx, ky) when 0 < k < 1 has what effect on the figure? What is the effect on the figure when k > 1?
