Answer 1

Answer:

• C. 1

Step-by-step explanation:

Given

• ΔABC with
• Slope of AB = -1
• ∠ABC = 90°

This means that AB⊥BC

The dilation doesn't affect the shape of the triangle, therefore:

• A'B' has slope of -1
• B'C' ⊥ A'B'

Perpendicular lines have negative reciprocal slopes. In other words the product of the slopes is  - 1.

Let the slope of B'C' is x, then:

• -1*x = -1
• x = 1

Correct option is C
