• 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
