1. Graph the original shape. ( In problems 1-4 this step is done for you)[br][br]2. multiply each coordinate point by the scale factor k[br][br]3. Plot the new points and connect them with line segments. Done![br][br]Example: graph (1,-2), (1, -4), (5, 3) and dilate by k=2[br]When you dilate: (1[color=#ff0000]*2[/color], -2[color=#ff0000]*2[/color]), (1[color=#ff0000]*2[/color], -4[color=#ff0000]*2[/color]), (5[color=#ff0000]*2[/color], 3[color=#ff0000]*2[/color]) =[color=#ff0000](2, -4) (2, -8) (10, -6)[/color]

example 2: graph triangle (12, 3) (12, 9) (6, 6) and dilate k = 1/3[br]When you dilate (12[color=#ff0000]/3[/color], 3[color=#ff0000]/3[/color]) (12[color=#ff0000]/3[/color], 9[color=#ff0000]/3[/color]) (6[color=#ff0000]/3[/color], 6[color=#ff0000]/3[/color]) = [color=#ff0000](4, 1) (4, 3) (2. 2)[/color]

1. Graph the triangle (2, 3) (5, 1) (5, 3) and dilate k = 3[br]

2. Graph the square (-16, 4) (-12, 0) (-8, 4) (-12, 8) and dilate k = 1/4

3. Graph the rectangle (1, -2) (7, -2) (7, -6) (1, -6) and dilate k = 2

4. Graph the triangle (-18, -6) (-15, -12) (-12, -6) and dilate k = 1/3

5. Graph the rectangle (2, 2) (2, 6) (4, 6) (4, 2) and dilate k=2

6. Graph the triangle ( -8, 4) (-16, 12) (-20, 8) and dilate k= 1/4
