Translations

Jean transformed a point by using the rule . The image point is (-4, 1). Which point is the -pre image

(2, -7)

The point (4, 5) is translated two units left and eight units down. What is the y-coordinate of the image?

-3

Which rule describes the translation below?

On a coordinate plane, point B(-6, 1) is translated to (-3, -2). Indira uses these steps to find a rule to describe the translation. Step 1Substitute the original coordinates and the translated coordinates into :Step 2Write two equations:Step 3Solve each equation:Step 4Write the translation rule: Which corrects Indira's first error?

Indira should have written the equations and in Step 2.

Four students are trying to find the rule that translates point N(-2, -4) to . Each student's reasoning is shown below. Raheem:The rule is because and .Casey:The rule is because the image is (2, 4).Andrew:The rule is because the coordinates are opposites.Lo:The rule is because and . Which student is correct?

Lo

Ryan wants to describe the translation shown on the grid below.Ryan uses the following steps to describe the translation. Step 1Identify the pre-image and the image:The pre-image is triangle XYZ, and the image is .Step 2Identify the number of units that each point moves horizontally:Each point moves one unit left.Step 3Identify the number of units that each point moves vertically:Each point moves three units down.Step 4The translation is one unit left and three units down. In which step did Ryan make the first error?

Step 3

Which rule describes the translation below?
