1/5 CW PreAlg 8-1 Skills and 2-3 Skills

We are starting on the 8-1 Translation side. This is #1

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y-3\right)$

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y+3\right)$

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y-3\right)$

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y+3\right)$

We are starting on the 8-1 Translation side. This is #2

• $\left(x,\ y\right)\rightarrow\left(x+4,\ y+1\right)$

• $\left(x,\ y\right)\rightarrow\left(x+1,\ y+4\right)$

• $\left(x,\ y\right)\rightarrow\left(x-4,\ y-1\right)$

• $\left(x,\ y\right)\rightarrow\left(x-1,\ y-4\right)$

We are starting on the 8-1 Translation side. This is #3

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y+1\right)$

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y-1\right)$

• $\left(x,\ y\right)\rightarrow\left(x+1,\ y+2\right)$

• $\left(x,\ y\right)\rightarrow\left(x-1,\ y-2\right)$

We are starting on the 8-1 Translation side. This is #4

• $\left(x,\ y\right)\rightarrow\left(x+1,\ y+4\right)$

• $\left(x,\ y\right)\rightarrow\left(x+4,\ y+1\right)$

• $\left(x,\ y\right)\rightarrow\left(x-1,\ y-4\right)$

• $\left(x,\ y\right)\rightarrow\left(x+1,\ y+4\right)$

We are starting on the 8-1 Translation side. This is #5

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y-5\right)$

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y-5\right)$

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y+5\right)$

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y+5\right)$

We are starting on the 8-1 Translation side. This is #6

• $\left(x,\ y\right)\rightarrow\left(3x,\ 3y\right)$

• $\left(x,\ y\right)\rightarrow\left(x-3,\ y-3\right)$

• $\left(x,\ y\right)\rightarrow\left(x+3,\ y+3\right)$

• $\left(x,\ y\right)\rightarrow\left(\frac{x}{3},\ \frac{y}{3}\right)$

We are starting on the 8-1 Translation side. This is #7

• $\left(x,\ y\right)\rightarrow\left(1x,\ 4y\right)$

• $\left(x,\ y\right)\rightarrow\left(x+1,\ y-4\right)$

• $\left(x,\ y\right)\rightarrow\left(4x,\ 1y\right)$

• $\left(x,\ y\right)\rightarrow\left(x-1,\ y+4\right)$

Now we are on the 2-3 Side. This is #1

• $\left(x,\ y\right)\rightarrow\left(x+\frac{1}{2},\ y+\frac{1}{2}\right)$

• $\left(x,\ y\right)\rightarrow\left(x-\frac{1}{2},\ y-\frac{1}{2}\right)$

• $\left(x,\ y\right)\rightarrow\left(2x,\ 2y\right)$

• $\left(x,\ y\right)\rightarrow\left(\frac{x}{2},\ \frac{y}{2}\right)$

Answer explanation

$\frac{x}{2}$ is the exact same thing as $\frac{1}{2}x$
Since the scale factor is less than one, this is a reduction
$\left(it\ gets\ smaller\right)$

Now we are on the 2-3 Side. This is #2

• $\left(x,\ y\right)\rightarrow\left(x+2,\ y+2\right)$

• $\left(x,\ y\right)\rightarrow\left(2x,\ 2y\right)$

• $\left(x,\ y\right)\rightarrow\left(x-2,\ y-2\right)$

• $\left(x,\ y\right)\rightarrow\left(\frac{x}{2},\ \frac{y}{2}\right)$

Answer explanation

Since the scale factor is bigger than one, this is an enlargement

Now we are on the 2-3 Side. This is #3

• $\left(x,\ y\right)\rightarrow\left(x+\frac{1}{3},\ y+\frac{1}{3}\right)$

• $\left(x,\ y\right)\rightarrow\left(3x,\ 3y\right)$

• $\left(x,\ y\right)\rightarrow\left(x-\frac{1}{3},\ y-\frac{1}{3}\right)$

• $\left(x,\ y\right)\rightarrow\left(\frac{1}{3}x,\ \frac{1}{3}y\right)$

Answer explanation

Since the scale factor is less than one, this is a reduction
