Complete the equation of the line through (-9,-9)(−9,−9)left parenthesis, minus, 9, comma, minus, 9, right parenthesis and (-6,0

saw5 [17]

Answer:

The equation of the line is;

y = 3x + 18

Step-by-step explanation:

We want to write the equation of the line through (-9,-9) and (-6,0)

we start by calculating the slope of the line

m = (y2-y1)/(x2-x1) = (0+ 9)/(-6+9) = 9/3 = 3

The general equation of the line is;

y = mx + c

y = 3x + c

To get c, we use any of the points

we substitute for example -6 for x and 0 for y

0 = 3(-6) + c

c = 0 + 18 = 18

So the equation of the line is;

y = 3x + 18

If an image of a triangle is congruent to the pre-image, what is the scale factor of the dilation?

likoan [24]

Answer:

The scale factor is 1.

Step-by-step explanation:

Let k be the scale factor of a dilation of triangle ABC to form the image triangle A'B'C'.

The dilation is a magnification if

$|k| > 1$

In this case, the preimage will be similar to the image triangle.

$- 1\: < \: k \: < \: 0 \: \: or \: \: 0 \: < \: k \: < \: 1$

the dilation is a reduction. The image and pre-image will still be similar.

But if

$k = 1$

the image is the same as the preimage.

We say the pre-image is congruent to the image triangle.
