**Part 1**

Are the lines in the questions below perpendicular to each other?

1) A: *y* = 4*x* – 7 B: *y* = -¼ *x* + 3

2) C: *y* = -2*x* D: *y* = ½ *x* + 3

3) E: *y* = 3*x* + 5 F: *y* = -2*x* + 5

4) G: *y* = 3*x* + 2 H: *y* = ^{1}/_{3} *x* + 2

5) I: 2*y* + 4*x* = 3 J: 2*y* + 8 = *x*

**Part 2**

__1) We have two lines; line 1 and line 2. Line 1 has the equation __*y* = 4*x* – 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* = m*x* + c.

2) We have two more lines; line A and line B. Line A has the equation 2*y* + 4*x* + 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* = m*x* + c.
