Answer:

18+2x

Step-by-step explanation:

Let the number be x.

Translate: 2x + 18 = x - 4.

Subtract x from each side:  x + 18 = -4.

Subtract 18: x = -22.

Check:  2(-22) + 18 = -44 + 18 = -26;  -22 - 4 = -26.

Slope=9

i)

y−y1=m(x−x1)

When line is parallel

y+5=9(x-6)

y+5 = 9x - 54

<h3>59 = 9x-y </h3>

When line is perpendicular

y+5=-1/9(x-6)

9(y+5)= -1(x-6)

9y + 45 = -x+6

<h3>x+9y = -39</h3>
