Question

A triangle with point A(4, -8) has a scale factor of -3/4

Find the coordinates for A’.

Enter the answer as a point (x, y)

Answer 1

The coordinates for A' is
`(-3,6)`

Step-by-step explanation:

Given that a triangle with point A has coordinate
`(4,-8)`

It has a scale factor of
`-(3)/(4)`

We need to determine the coordinates for A'

The coordinates for A' can be determined by multiplying the scale factor with both the x and y coordinates of A

Let us consider the x - coordinate of A.

x - coordinate of A' =
`4*(-(3)/(4) )`

=-3

Thus, the x - coordinate of A' is -3

Let us consider the y - coordinate of A.

y - coordinate of A' =
`-8*(-(3)/(4) )`

= 6

Thus, the y - coordinate of A' is 6

Therefore, the coordinates of A' is
`(-3,6)`
