 (–5,–7) _____ (4,–2) _____ (–8,3) _____ (6,6) _____

#### Solutions

 (–5,–7) _____III_____ (4,–2) _____IV_____ (–8,3) _____II_____ (6,6) _____I_____

### Practice 2

#### Problems

1. What is the slope between the points (2,3) and (–3,4)?
2. What is the slope between the points (–3,6) and (–1,–4)?
3. What is the distance between the points (1,2) and (–5,10)?
4. What is the distance between the points (–8,16) and (–3,4)?
5. What is the midpoint between the points (3,5) and (1,3)?
6. What is the midpoint between the points (–4,–2) and (0,6)?

#### Solutions

1. Read and understand the question. This question is looking for the slope between two points.
2. Make a plan. Use the formula and substitute the coordinates of the two points. Use (2,3) as (x1,y1) and (–3,4) as (x2,y2). Carry out the plan. The formula becomes

The slope is –

Check your answer. To check this result, substitute the values in the opposite order to make sure that the slope is the same. The formula is

This result is checking.
