3.3 Notes B
1. Opener: Refer to the coordinate graph on the left and answer the
following questions:
Do in your notes.
1.) Where can you find a point whose x‐coordinate is
negative? positive? zero?
2.) Where can you find a point whose y‐coordinate is
negative? positive? zero?
3.) Where can you find a point whose x‐coordinate is 8?
4.) Where can you find a point whose y‐coordinate is ‐6?
5.) Where can you find a point whose y‐coordinate is less
than its x‐coordinate?

3. Day 32: 3.3 Distance and Absolute Value
Launch: Work with your partner to find the distance between
each pair of points. (*Hint: A good starting place is to
Finding the distance sketch the points on a graph).
between 2 points.
1. (‐1, ‐3) and (4, ‐3) 2. (‐1, ‐3) and (‐1, 9)
3. (2, 1) and (‐3, 1) 4. (2, 1) and (2, ‐16)
How did you calculate the distance above?
What is the easiest way to calculate distance
between two numbers?
** Distance is always ______________.

4. Defining Absolute
Value: The absolute value of (x ‐ y) is the _____________
between the numbers x and y.
• Commonly written in the form:
Consider the following examples.
a.) 8 ‐ 3 and 3 ‐ 8
b.) 1 ‐ (‐ 5) = 6 and ‐ 5 ‐ 1 = 6

5. Calculating Now try these individually and then check your
Absolute Value: answers with your partner. ( 4 minutes)
1. (‐6) ‐ 0 2. (‐2) ‐ 6
3. 4 ‐ 10 4. (‐3) ‐ (‐5)
