Lesson 6.2Slope-Intercept Form

Objective 1: Writing Linear Equations

Linear Equation – an equation whose graph is a straight line when graphed

Y-Intercept – Where a line crosses the y-axis (0, y)

Slope-Intercept Form

y = mx + b

slope y-intercept

Y = 3x – 6 Y = -4x + 7 2x + 3Y = 6

Slope = -3 and y-int = 5 slope = 2/3 and y-int = -9
