Question

The slope of A’B

1.2
-1.2
-3.6

The length of A’C
1/3 q units
3 q units
-1.2 p units
(p + q + r) units

Answer 1

`-1.2.`

`3q.`

Explanation:

The dilation is the transformation that maps lines into parallel lines. Parallel lines always have the same slope, thus the slope of A'B' is
`-1.2.`

If a scale factor is 3, then all sides of the triangle A'B'C' are three times longer than corresponding sides of the triangle ABC. Hence, if the length of the side AC is
`q,` then the length of the side A'C' is
`3q.`
