Are the lines y = –x + 8 and 3x + 3y = 9 perpendicular? Explain.

Mathematics
1 answer:
GarryVolchara [31]4 years ago
5 0

Answer:

No

Step-by-step explanation:

Rearrange the equations to match the linear y=mx+b

1. 3x + 3y = 9

y = -x +3

2. y = -x + 8

y = -x + 8

Since the two equations have the same slope, they are parallel, not perpendicular.

Write an equation of the line that passes through the point(-6,-9) with slope -5
LUCKY_DIMON [66]

Answer:

  y = -5(x +6) -9

Step-by-step explanation:

The point-slope form of the equation for a line can be written as ...

  y = m(x -h) +k

for a line with slope m through point (h, k).

You have m=-5 and (h, k) = (-6, -9). Filling in these values gives ...

  y = -5(x -(-6)) -9

Simplifying a bit, you get ...

  y = -5(x +6) -9

Devon's sister is incorrect.

Note 6 drinks thats cost $2.99
