1.) y = 1/2x -1.8 slope is 1/2 and y intercept is - 1.8

Step-by-step explanation:

1.) 5x - 10y = 18

 +10y         +10y

5x = 10y +18

- 18         -18

5x - 10y = 18

  10          10

= 1/2x -1.8

1/2

Step-by-step explanation:

First, you should simplify the equation. y - 2 = -2(x + 6) --> y = -2x - 12 +2 = -2x -10. The slope of this side is -2. The slope of the side adjacent to it should be perpendicular to this side, so it should be 1/2.
