YIP !!!! Slope = ____ or _____ or _____ YIP: Slope of a line is its ________________ The following example describes how slope (rate of change) is applied. YIP: Rate of change is also know as _____ over ______. Δ means _________ YIP !!!! Slope = ____ or _____ or _____

IN CLASS WORK MR YACK, GO over it with Class

FOLDABLE!!!! YIP: If an equation is linear, a constant change in the x-value corresponds to a constant change in the y-value. The graph shows an example where each time the x-value increases by 3, the y-value increases by 2. Slope = 2 3

2) Find the slope of the line that passes through the points (-2, -2) and (4, 1). When given points, it is easier to use the formula! y2 is the y coordinate of the 2nd ordered pair (y2 = 1) y1 is the y coordinate of the 1st ordered pair (y1 = -2)

Find the slope of the line that passes through each pair of points Find the slope of the line that passes through each pair of points. Call kids up to the board (1, 3) and (2, 4) (0, 0) and (6, -3) (2, -5) and (1, -2) (3, 1) and (0, 3) (-2, -8) and (1, 4) m = 1 2) m = -1/2 3) m = -3 4) m = -2/3 5) m = 4

Remember, linear equations have constant slope Remember, linear equations have constant slope. For a line on the coordinate plane, slope is the following ratio. This ratio is often referred to as “rise over run”.

YIP: Draw the graph and find the slope of the line.

Given the point (4, 2), find the slope of this line?

5) Which is the slope of the line through (-2, 3) and (4, -5)? -4/3 -3/4 4/3 -1/3

Find the slope of the line that passes through (3, 5) and (-1, 4). -4 ¼ - ¼

3) The slope of this line is 3/2? True False
