Answer:

-13

Step-by-step explanation:

Explanation:

We must first find the slope of the given line.

x+2y=8

2y=

8−xy=4−12x

So, the perpendicular line's slope is the opposite inverse of the given line, or

2.

Since we are given that it passes through a point, we may use point-slope to write out the line.

Point-Slope:

y−y0=m(x−x0)

Plugging in,

y−(−9)=2(x−2[y=2x−4−9y=2x −13

We can now graph this.
