Answer:

1) y = - 5/3x

2) y = - 4/3x

3) slope = - 1/17

4) slope = 6

6) y = -x - 1

7) y = -3/5x - 1/5

8) y = -x - 7

Explanation:

5x + 3y = 0

3y = 0 - 5x

y = 0/3 - 5/3x or…

y = - 5/3x
- - - - - - - - - - - - - - - - -
4x + 3y = 0

3y = 0 - 4x

y = 0/3 - 4/3x or…

y = - 4/3x
- - - - - - - - - - - - - - - - -
(4, -9) , (-13, -8)

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (-8 - -9)/(-13 - 4)

m = 1/-17 or…

m = - 1/17
- - - - - - - - - - - - - - - - -
(8, 12) , (5, -6)

m = slope

m = change in y/change in x

m = (y2 - y1)/(x2 - x1)

m = (-6 - 12)/(5 - 8)

m = -18/-3

m = 18/3 or…

m = 6

6)

y = -x - 1

through (3, -2), parallel
to y = -3/5x

y = -3/5x + b

-2 = -3/5(3) + b

-2 = -9/5 + b

b = -2 - -9/5

b = - 1/5

The line would be y = -3/5x - 1/5
- - - - - - - - - - - - - - - - -
y = -x

(-5, -2)

-2 = 5 + b

b = -2 - 5

b = -7

The line would be y = -x - 7
