1. Use the slope formula to answer Parts I, II, and III.
Part I: Find the slope of the line that passes through the following points. (6 points; 2 points
each)
A (10,4) and B (-2 , -5) C (-7 ,1) and D (7, 8)

Part a) The slope of line that passes through the points A (10,4) and B (-2 , -5) is

Part b) The slope of line that passes through the points C (-7 ,1) and D (7, 8) is

Step-by-step explanation:

Part I: Find the slope of the line that passes through the following points.

Part a)

A (10,4) and B (-2 , -5)

We need to find slope of the line that passes through the given points.

The formula used is:

We can take any two points and the slope will be same.

I am taking points A (10,4) and B (-2 , -5)  and finding slope

We have

Putting values and finding slope

So, the slope of line that passes through the points A (10,4) and B (-2 , -5) is

Part a)

C (-7 ,1) and D (7, 8)

We need to find slope of the line that passes through the given points.

The formula used is:

We can take any two points and the slope will be same.

I am taking points C (-7 ,1) and D (7, 8)  and finding slope

We have

Putting values and finding slope

So, the slope of line that passes through the points C (-7 ,1) and D (7, 8) is
