Answer:

The coordinates of  A'(8,-5)

Step-by-step explanation:

we know that

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places

so

The rule of the reflection across the line y=x is

(x,y) -----> (y,x)

we have the point A(-5,8)

Applying the rule of the reflection across the line y=x

A(-5,8) ----> A'(8,-5)

see the attached figure to better understand the problem

Step-by-step explanation:

<u>Step 1: Define</u>

Point (1, -3)

Point (0, -1)

<u>Step 2: Find slope </u><em><u>m</u></em>

Substitute in points into the slope formula to find rate of change

  1. Substitute [SF]:                    m=\frac{-1+3}{0-1}
  2. Add/Subtract:                      m=\frac{2}{-1}
  3. Divide:                                 m=-2
