Question

4 pentagon a is graphed on the coordinate grid. pentagon a will be transformed using the rule (x, y) → (x+5, y−2) to create pentagon b. graph pentagon b the on the grid. move a pentagon to the correct position. not all answers will be used.

Explanation:

Step1: Identify vertices of Pentagon A

First, we need to find the coordinates of the vertices of Pentagon A. Let's assume the vertices of Pentagon A (from the graph) are, for example, let's take the key points: let's say the leftmost point is (7, 4), the bottom - left corner, the bottom - right corner is (11, 4), the right - most top point, and the top point and the left - most top point. But more systematically, let's find the coordinates of each vertex. Looking at the graph, the vertices of Pentagon A (approximate, since it's a grid) are: let's list them as \((x_1,y_1)=(7,4)\), \((x_2,y_2)=(11,4)\), \((x_3,y_3)=(12,6)\), \((x_4,y_4)=(9,7)\), \((x_5,y_5)=(6,6)\) (these are approximate coordinates based on the grid, we can also use the fact that the transformation is a translation).

Step2: Apply the transformation rule \((x,y)\to(x + 5,y-2)\)

For each vertex \((x,y)\) of Pentagon A, we apply the rule.

  • For \((x_1,y_1)=(7,4)\):

New \(x\) - coordinate: \(x_1+5=7 + 5=12\)
New \(y\) - coordinate: \(y_1-2=4-2 = 2\)
So the new vertex is \((12,2)\)

  • For \((x_2,y_2)=(11,4)\):

New \(x\) - coordinate: \(x_2 + 5=11+5 = 16\)
New \(y\) - coordinate: \(y_2-2=4 - 2=2\)
New vertex: \((16,2)\)

  • For \((x_3,y_3)=(12,6)\):

New \(x\) - coordinate: \(x_3+5=12 + 5=17\) (Wait, but the grid goes up to \(x = 16\), maybe my initial coordinates were wrong. Let's re - examine. Let's take the correct coordinates. Let's look at the blue pentagon A:
The left - bottom vertex: Let's say the \(x\) - coordinate is 7, \(y\) - coordinate is 4.
The right - bottom vertex: \(x = 11\), \(y = 4\)
The right - top vertex: \(x = 12\), \(y = 6\)
The top vertex: \(x = 9\), \(y = 7\)
The left - top vertex: \(x = 6\), \(y = 6\)

Wait, maybe a better way: the translation rule \((x,y)\to(x + 5,y - 2)\) means we move each point 5 units to the right (since \(x\) increases by 5) and 2 units down (since \(y\) decreases by 2).

So, to graph Pentagon B, we take each vertex of Pentagon A, add 5 to the \(x\) - coordinate and subtract 2 from the \(y\) - coordinate, then plot these new points and connect them.

For example, if a vertex of A is \((x,y)\), the corresponding vertex of B is \((x + 5,y-2)\).

So, if we consider the general process:

  1. Find all vertices of Pentagon A.
  2. For each vertex \((x,y)\), compute \((x + 5,y-2)\).
  3. Plot these new points and form Pentagon B.

Visually, moving each point of A 5 units right and 2 units down. So the green pentagon B should be placed such that each of its vertices is 5 units right and 2 units down from the corresponding vertices of A.

Answer:

To graph Pentagon B, take each vertex of Pentagon A, apply the transformation \((x,y)\to(x + 5,y - 2)\) (move 5 units right and 2 units down), and then plot and connect the new vertices. The green pentagon B should be positioned with its vertices at \((x+5,y - 2)\) relative to the vertices of Pentagon A. (In terms of the grid, if we assume the vertices of A are, for example, (7,4), (11,4), (12,6), (9,7), (6,6), then the vertices of B are (12,2), (16,2), (17,4), (14,5), (11,4) (after correcting the \(y\) - coordinate calculation: \(y-2\), so for \(y = 6\), it's \(6 - 2=4\); for \(y = 7\), it's \(7 - 2 = 5\)) and then connect these points to form Pentagon B.)
