Answer:
Use the value for the variable to solve for the other unknowns. Substitute the value for the variable into the expression for the number of seats on the middle level. Substitute the value for the variable into the expression for the number of seats on the lower level.

The point-slope form of the equation of a line is
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=%20y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29%20)
where
is a point on the line, and
![m](https://tex.z-dn.net/?f=%20m%20)
is the slope of the line.
We can use either one of the two given points as the point on the line.
We also need to find the slope. We can use the coordinates of the two given points to find the slope of the line.
The slope of the line that passes through points
![(x_1, y_1)](https://tex.z-dn.net/?f=%20%28x_1%2C%20y_1%29%20)
and
![(x_2, y_2)](https://tex.z-dn.net/?f=%20%28x_2%2C%20y_2%29%20)
is
![m = \dfrac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cdfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20)
Let's find the slope using (-3, 5) as point 1 and (-1, 4) as point 2.
![m = \dfrac{4 - 5}{-1 - (-3)} = \dfrac{-1}{-1 + 3} = \dfrac{-1}{2} = -\dfrac{1}{2}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cdfrac%7B4%20-%205%7D%7B-1%20-%20%28-3%29%7D%20%3D%20%5Cdfrac%7B-1%7D%7B-1%20%2B%203%7D%20%3D%20%5Cdfrac%7B-1%7D%7B2%7D%20%3D%20-%5Cdfrac%7B1%7D%7B2%7D%20)
Now we use the point-slope formula with point 1 and the slope we found just above.
![y - y_1 = m(x - x_1)](https://tex.z-dn.net/?f=%20y%20-%20y_1%20%3D%20m%28x%20-%20x_1%29%20)
Start at one of the vertices and draw a line from there to a point on the oposite side, not ending at another vertex
Answer:
Yes, triangle GYK is similar to triangle BAK.
Step-by-step explanation:
The sides of each triangle are proportional to each other.
Take the longest side of each triangle. You are comparing line AK with line KY.
The proportion is 15/25.
Now, take the shortest side of each triangle. You are comparing line KB with GK.
The proportion is 6/10.
To determine if the triangles are proportional, we can see if the two proportions are equal to each other:
15/20=6/10
3/5=6/10
Correct! 3/5 equals to 6/10. Therefore, the two triangles are similar because their sides are proportional.
Hope this helps :)
