• Slope- Rate of change or direct variation of:

• Slope is read from left to right • Can be a fraction, decimal, or integer

Types of slope

Negative slope goes down from left to right (downhill)

• Positive slope goes up from left to right (uphill)

Finding Slope (given a graph)

Will it be positive or negative?

Finding Slope (given a graph)

Will it be positive or negative?

Finding Slope (given 2 points)

• The points (3, 2) and (5 ,4 ) pass through a line. Their slope is 1. How did they get that?

Finding Slope (given 2 points)

• The points (4,1) and (6,0) pass through a line. Their slope is -1/2. How did they get that?

Solo-Pair Consensus

1. Find a partner and either sit next to them or facing them

2. Do the problem on the screen alone3. When I tell you, discuss it with your partner

Find the slope

3/2 or 1.5

Find the slope

-5/2 or -2.5

Find the slope

-4/1 or -4

Find the slope

• The points (1, 3) and (3,7) go through the same line.

• ( 4/2 or 2)

Find the slope

• The points (3, 2) and (1,3) go through the same line.

• ( -1/2 or -0.5)

Find the slope

• The points (-2, 4) and (1,0) go through the same line.

• ( -4/3 or -1.33)

Find the missing coordinate

• Two points on a line are (2,4) and (x, 8). If the line has a slope of -2, what is the value of x?

• X = 0

Find the missing coordinate

• Two points on a line are (4,3) and (5,y). If the line has a slope of 3, what is the value of y?

• Y=6

Find the missing coordinate

• Two points on a line are (3,y) and (1,9). If the line has a slope of -5/2, what is the value of y?

• Y=4
