 Rewrite the following in Slope Intercept Form a. 5x – 6y = 18 b. 3y – 8x = 15  Find the slope of the line containing the points (1, -3) and (6, -8)  Given the equation y = 2/3x – 8; Identify the slope and the y-intercept  Graph the following 2 lines a. y = 1/4x – 3 b. y = -3x + 6  Find the equation of the line by graphing the following two points. (3, 2) and (-3, 0)

 Slope Intercept form y = mx + b slope =  Standard Form Ax + By = C y-intercept Starting point when graphing

 Finding Slope given a graph  Finding Slope Given Two Points (6, -3) and (-4, 8) Create a chart xy

 Below is John’s football stats.  What is his yards per carry carriesyards Calculate Slope – 8 yards per carry

Step 1 – Find the Slope Step 2 – Find the y-intercept b = -3 Put the equation together using the data y = mx + b y = 3/2x - 3

 Standard Form Ax + By = C  x – intercept is when the y value is zero  y – intercept is when the x value is zero Example: -2x + 6y = 24 To find the x-intercept cover y and solve for x -2x = 24 therefore intercept is (-12,0) To find the y-intercept cover x and solve for y 6y = 24 therefore intercept is (0,4) Line intersects the axis at (-12,0) and (0,4)

 Rewrite the following in slope intercept form and then identify the slope and y-intercept of the line a. 4x – 7y = 42 b. 4y – 12x + 16 = 0  Find the equation of the line containing the following two points: (4, -1) and (-4, -7)
