Linear Graphs: Quiz 12
Part 1
Are the lines in the questions below perpendicular to each other?
1) A: y = 4x – 7 B: y = -¼ x + 3
2) C: y = -2x D: y = ½ x + 3
3) E: y = 3x + 5 F: y = -2x + 5
4) G: y = 3x + 2 H: y = 1/3 x + 2
5) I: 2y + 4x = 3 J: 2y + 8 = x
Part 2
1) We have two lines; line 1 and line 2. Line 1 has the equation y = 4x – 14. Line 2 is perpendicular to line 1 and they both pass through the point (4, 2). What is the equation for line 2? Give your answer in the form of y = mx + c.
2) We have two more lines; line A and line B. Line A has the equation 2y + 4x + 4 = 0. Line A and line B are perpendicular to each other and they both pass through the point (-4, 6). What is the equation of line B? Give your answer in the form y = mx + c.
