Answer:
(8,9)
Step-by-step explanation:
Given
![A = (2,6)](https://tex.z-dn.net/?f=A%20%3D%20%282%2C6%29)
![B = (2,9)](https://tex.z-dn.net/?f=B%20%3D%20%282%2C9%29)
![C = (8,6)](https://tex.z-dn.net/?f=C%20%3D%20%288%2C6%29)

Determine the 4th point
The coordinate point of a horizontal or a vertical rectangle is given as:
(x1,y1), (x2,y2), (x3,y3), (x4,y4)
Where:
![y_2 = y_4](https://tex.z-dn.net/?f=y_2%20%3D%20y_4)
So, we have:
--- ![(x_1.y_1)](https://tex.z-dn.net/?f=%28x_1.y_1%29)
---- ![(x_2.y_2)](https://tex.z-dn.net/?f=%28x_2.y_2%29)
---- ![(x_3,y_3)](https://tex.z-dn.net/?f=%28x_3%2Cy_3%29)
Using the above equations:
![x_3 = x_4](https://tex.z-dn.net/?f=x_3%20%3D%20x_4)
![= 9](https://tex.z-dn.net/?f=%3D%209)
Hence, the coordinate of the 4th point is:
![(x_4,y_4) = (8,9)](https://tex.z-dn.net/?f=%28x_4%2Cy_4%29%20%3D%20%288%2C9%29)

Answer:
the desired equation is y = (3/5)x + 4
Step-by-step explanation:
Solving the given 5x + 3y = -21 for 3y yields 3y = -5x - 21. Dividing all three terms by 3, we get:
y = (-5/3)x - 7, indicating that the given line has slope -5/3.
The slope of a line perpendicular to this y = (-5/3)x - 7 is 3/5, the negative reciprocal of -5/3.
Start with y = mx + b. Substitute 1 for y, -5 for x and 3/5 for m. Then:
1 = (3/5)(-5) + b, or
1 = -3 + b. Then b must be 4, and so the desired equation is y = (3/5)x + 4.
