Answer:
parallel:
perpendicular:
Step-by-step explanation:
original line:
-7x + 8y = 4
m = 7/8
parallel:
m = 7/8
L: 7x - 8y = k
(4, -4) -> L
28 + 32 = 60 = k
L: 7x - 8y = 60
perpendicular:
m = -8/7
L: -8x + 7y = k
(4, -4) -> L
-32 + 28 = -4 = k
L: -8x -7y = -4
=> 8x + 7y = 4
- We need to rearrange this into
- Subtract 14x from both sides
- Divide both sides by 2
- Divide both sides by 9
- Plot the point (0, 63/9)
- Then pick some x values and put them into the equation to find the respective y values
- Then plot those points
- Finally join up those points
