2. Chapter 5 Review 1)Write the equation of the line (in slope intercept form) that goes through the given point with the given slope. a) (4,6); m = -5 b) (8,5); m = ½

3. Chapter 5 Review 1)Write the equation of the line (in slope intercept form) that goes through the given point with the given slope. a) (4,6); m = -5 b) (8,5); m = ½ Answer y = -5x + 26 y = ½ x + 1

4. Chapter 5 Review 2)Write an equation of the line that goes through (1,6) and (9, -4) in, a) point-slope form b) slope-intercept form c)General (Ax + By = C) form

5. Chapter 5 Review 2)Write an equation of the line that goes through (1,6) and (9, -4) in, a) point-slope form b) slope-intercept form c)General (Ax + By = C) form Answer y − 6 = -5 / 4 (x – 1) or y + 4 = -5 / 4 (x – 9) y = -5 / 4 x + 29 / 4 5 / 4 x + y = 29 / 4 or 5x + 4y = 29

6. Chapter 5 Review 3)Write an equation in slope-intercept form for the line… a)parallel to y = 4x + 1 through (-3, 5) b)perpendicular to 3x + 4y = 12 through (7, 1)

7. Chapter 5 Review 3)Write an equation in slope-intercept form for the line… a)parallel to y = 4x + 1 through (-3, 5) b)perpendicular to 3x + 4y = 12 through (7, 1) Answer y = 4x + 17 y = 4 / 3 x − 25 / 3

8. Chapter 5 Review 4)Tell whether the following lines are ││, , or neither to y = 3 / 5 x + 3 a) y = -3x + 5 b) y = -5 / 3 x + 5 / 3

9. Chapter 5 Review 4)Tell whether the following lines are ││, , or neither to y = 3 / 5 x + 3 a) y = -3x + 5 b) y = -5 / 3 x + 5 / 3 Answer Neither perpendicular

10. Chapter 5 Review 5)Tell whether the following lines are ││, , or neither to y = 3 / 5 x + 3 a) 3x − 5y = 10 b) 5y + 3x = 15

11. Chapter 5 Review 5)Tell whether the following lines are ││, , or neither to y = 3 / 5 x + 3 a) 3x − 5y = 10 b) 5y + 3x = 15 Answer parallel neither
