Answer:
Step-by-step explanation:
b would be 0
your slope is rise/run. up one and over three. up one and over three. so 1/3
write it as y=1/3x+0, or y=1/3x
2y - 18x = -26
Add 18x to both sides.
2y = -26 + 18x
Divide by 2 on both sides.
y = -13 + 9x
y = 9x - 13
Answer: 
======================================================
Explanation:
Method 1
We can use the pythagorean theorem to find x.

-----------------------------------
Method 2
Use the sine ratio to find x. You'll need a reference sheet or the unit circle, or simply memorize that sin(60) = sqrt(3)/2

-----------------------------------
Method 3
Similar to the previous method, but we'll use tangent this time.
Use a reference sheet, unit circle, or memorize that tan(60) = sqrt(3)

-----------------------------------
Method 4
This is a 30-60-90 triangle. In other words, the angles are 30 degrees, 60 degrees, and 90 degrees.
Because of this special type of triangle, we know that the long leg is exactly sqrt(3) times that of the short leg.

The short leg is always opposite the smallest angle (30 degrees).
use cross products to solve
5* (n-9) = 8*n
distribute
5n-45 = 8n
subtract 5n from both sides
-45 = 3n
divide both sides by 3
-15 = n
