Answer:
12/3 or 4
Step-by-step explanation:
When solving for a constant use the equation y/x. All you need to do is find the y coordinate and the x coordinate and divide the 2.
Plugin 12 for y and 3 for x
The answer would be 12/3 or 4
You would want to plug in the 12 for y and 3 for x

Answer:
![y =- 3/2x + 4](https://tex.z-dn.net/?f=y%20%3D-%203%2F2x%20%2B%204)
Step-by-step explanation:
![(2,1) and (6,-5).\\x_1 = 2\\x_2 = 6\\y_1 =1\\y_2 =-5\\\frac{y-y_1}{x-x_1} = \frac{y_2-y_1}{x_2-x_1}\\ \\\frac{y-1}{x-2} = \frac{-5-1}{6-2}\\\\\frac{y-1}{x-2} = \frac{-6}{4} \\Cross-Multiply\\4(y-1) = -6(x-2)\\4y-4=-6x+12\\4y =-6x+12+4\\4y = -6x+16\\Divide- through-by ; 4\\\frac{4y = -6x+16}{4} \\\\y = -\frac{3}{2} x +4](https://tex.z-dn.net/?f=%282%2C1%29%20and%20%286%2C-5%29.%5C%5Cx_1%20%3D%202%5C%5Cx_2%20%3D%206%5C%5Cy_1%20%3D1%5C%5Cy_2%20%3D-5%5C%5C%5Cfrac%7By-y_1%7D%7Bx-x_1%7D%20%3D%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5C%20%5C%5C%5Cfrac%7By-1%7D%7Bx-2%7D%20%3D%20%5Cfrac%7B-5-1%7D%7B6-2%7D%5C%5C%5C%5C%5Cfrac%7By-1%7D%7Bx-2%7D%20%3D%20%5Cfrac%7B-6%7D%7B4%7D%20%5C%5CCross-Multiply%5C%5C4%28y-1%29%20%3D%20-6%28x-2%29%5C%5C4y-4%3D-6x%2B12%5C%5C4y%20%3D-6x%2B12%2B4%5C%5C4y%20%3D%20-6x%2B16%5C%5CDivide-%20%20through-by%20%3B%204%5C%5C%5Cfrac%7B4y%20%3D%20-6x%2B16%7D%7B4%7D%20%5C%5C%5C%5Cy%20%3D%20-%5Cfrac%7B3%7D%7B2%7D%20x%20%2B4)

180÷6=30
Answer:
X = 2
Z = 95
Step-by-step explanation:
(A)6x+4x-6=24+9x
10x-6=24+9x
10x-9x=24+6
x=30. (only 1 solution)
(B)25-4x = 15-3x+10-x
25-4x = 5-4x
25-5 = 4x-4x
30 = 0 (No solution)
(C)4x+8 = 2x+7+2x-20
4x+8 = 4x -13
4x-4x = -13-8
0 = -21 (No solution)
