Answer:
Rule: dilation about the origin by a scale factor of 2
Step-by-step explanation:
Given
See attachment for QRST and Q'R'S'T
Required
The dilation rule
First, we calculate the scale factor (k)
From the attachment, we have:
k, is then calculated as:
<em>Hence, QRST is dilated by a factor of 2</em>
Answer:
A) up 5 units
Step-by-step explanation:
Given
See attachment for grid
Required
Which places ABCD in a quadrant
<u>Considering vertical movements</u>
From the x-axis, the distance between each point and the line of the x-axis is (the y coordinates):
Considering the highest magnitudes in the positive and negative column, we have:
and
means that a upward movement by (4 + 1) units will move ABCD completely in a quadrant;
<em>Hence, 5 units upward -- This represents option (a)</em>
means that a downward movement by (7 + 1) units will move ABCD completely in a quadrant
<em>Hence, 8 units downward</em>
<em />
<u>Consider horizontal movements</u>
From the y-axis, the distance between each point and the line of the x-axis is (the x coordinates):
Considering the highest magnitudes in the positive and negative column, we have:
means that a left movement by (8 + 1) units will move ABCD completely in a quadrant;
<em>Hence, 9 units upward </em>
<em />
<em>(a) answers the question</em>
