Line segment AB is dilated to create line segment A'B' using point Q as the center of dilation.
Mekhanik [1.2K]

The scale factor in the question given above is: 2 See the explanation below.

<h3>What is a scale factor?</h3>

In math, the scale factor is the extent or ratio by which a geometrical shape is enlarged or reduced.

<h3>What is the explanation for the above answer?</h3>

We know that:

  • The distance from point Q to point A is 1.25
  • The distance from point A to point A' is 1.25

Given the above, the distance from point Q to point A' is 2.50. This is double the distance from point Q to point A.

The scale factor is 2.

1.25 + 1.25 = 2.50

2.50 / 1.25 = 2

Slope of line that passes through points (2,1) and (17,-17)
mojhsa [17]

Answer: y = -1,2x + 3.4

Step-by-step explanation:

y = ax + b

(2,1)      => 1    = 2a + b (1)

(17,-17) => -17 =17a + b (2)

Using caculator Mode => 5 =>1

We get : a=- 1.2 , b = 3.4

=> y = -1.2x + 3.4
