New Vocab 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 alone 3.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
