Answer 1

Explicación paso a paso:

Ecua 01.

y = -2x + 4

m = -2

Ecua 02.

2x + y = -3

y = -2x - 3

m = -2

Ecua 03.

3y = 8x + 12

y = (8/3)x + 4

m = 8/3

Ecua 04.

y = 2x - 2

m = 2

Ecua 05.

2y = 3x - 6

y = (3/2)x - 3

m = 3/2

Ecua 06.

2y = 3x + 5

y = (3/2)x + 5/2

m = 3/2

Ecua 07.

-4y = -5x - 2

4y = 5x + 2

y = (5/4)x + 1/2

m = 5/4

Ecua 08.

2y = 3x + 7

y = (3/2)x + 7/2

m = 3/2

Ecua 09.

-4y = -x - 5

4y = x + 5

y = (1/4)x + 5/4

m = 1/4

Ecua 10.

-4y = -x + 3

4y = x - 3

y = (1/4)x - 3/4

m = 1/4

Ecua 11.

-2y = -4x - 10

y = 2x + 5

m = 2

Ecua 12.

6y = 2x + 8

y = (1/3)x + 4/3

m = 1/3
