Answer:

A'(-3, 12)
B'(9, 6)
C'(-6, -6)

Step-by-step explanation:

Dilation about the origin multiplies each coordinate value by the dilation factor.

For dilation factor k, the new coordinates are ...

(x, y) ⇒ (kx, ky)

Your dilation factor is 3, so the transformation is ...

(x, y) ⇒ (3x, 3y)

A(-1, 4) ⇒ A'(-3, 12)

B(3, 2) ⇒ B'(9, 6)

C(-2, -2) ⇒ C'(-6, -6)

Find the slope of the line passing through the points (8,-3) and (4,-1)

docker41 [41]

$\rm \to m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$\\ \\$

$\rm \to m = \dfrac{ - 1 - 3}{4 - 8}$

$\\ \\$

$\rm \to m = \dfrac{ - 4}{4 - 8}$

$\\ \\$

$\rm \to m = \dfrac{ - 4}{ - 4}$

$\\ \\$

$\rm \to m = \cancel \dfrac{ - 4}{ - 4}$

$\\ \\$

$\rm \to m = 1$
