Question

The table shows the proof of the relationship between the slopes of two parallel lines. What is the missing reason for step 2? A. application of the distance formula B. application of the slope formula C. transitive property D. Pythagorean theorem

Answer 1

The missing reason for step 2 is b. application of the slope formula

What is the missing reason for step 2?

From the question, we have the following parameters that can be used in our computation:

The proof of the line relationship

Where, we have that

The lines are perpendicular

In step 1, the given parameters are stated

This means that the next step is to apply the slope formula

This is done by:

`m_1 = (d - b)/(c - 0) = (d - b)/(c)`

`m_2 = (0 - a)/(c - 0) = -(a)/(c)`

Hence, the missing reason for step 2 is b. application of the slope formula
