6. 8.1-8.2 Equations of parallel and perpendicular lines EQ: How do you make conjectures about the slopes of parallel and perpendicular lines? Sub EQ1: How do you find the slope given two points? Slope = with points Ex: Find the slope with given points: 1.(-5, 1), (3, 1) 2.(-6, 0), (2, -4)

7. Sub EQ2: How do you find an equation of a line with given slope and a y-intercept? Ex: Slope = 4; y-intercept = 7 Sub EQ3: How do you find an equation of a line with given slope and a point? Ex: Slope = 2; (-1, -5)

8. Sub EQ4: How do you find an equation of a line with given two points? Ex: (-4, 5); (2, -1) Sub EQ5: How do you find an equation of a line that is parallel to a given line and passes through a given point? Ex: Parallel to y = 3x + 2; passes through (-1, -5)

9. Sub EQ6: How do you find an equation of a line that is perpendicular to a given line and passes through a given point? Ex: perpendicular to y = 3x + 2; passes through (-1, -5)
