Graphing

Information Slope intercept form: y = mx + b M = slope B = y-intercept Identify the slope and y-intercept Y = -2/3x + 3 Y = 2x – 4 Y = 4x + 3

Identify the slope and y-intercept Y = -2x + 5 Y = 4x - 8 Y = 3/4x + 7 Y = -3/5x - 28

Graph Y = -x + 1 3x – 2y = 6 Y = 4x

Graph Y = -3x 2x – 5y = 15 Y = 2x + 3

Identify the graphs Y = 2x + 1 Y = -2/3x – 1 Y = 3x + 2

Horizontal/Vertical lines Horizontal: line crosses y-axis. Vertical: line crosses x-axis Ex: x = 3, x = -2 y = 2, y = -5

Vertical/Horizontal Graphs-st Graph the following X = 2 Y = -4 X = -1

Slopes of Parallel and Perpendicular lines Find Parallel slope Use same slope Find perp. Slope Use opposite reciprocal of slope. 2x – 5y = 15 Y = 4x + 10

Find Parallel/perp. slope Y = -1/4x + 1 Y = -3x + 1
