Y= -2/6 +4 theyre decreasing because the slope is negative
        
             
        
        
        
Solving:
-7 + y = 3 + 2y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-2y' to each side of the equation.
-7 + y + -2y = 3 + 2y + -2y
Combine like terms: y + -2y = -1y
-7 + -1y = 3 + 2y + -2y
Combine like terms: 2y + -2y = 0
-7 + -1y = 3 + 0
-7 + -1y = 3
Add '7' to each side of the equation.
-7 + 7 + -1y = 3 + 7
Combine like terms: -7 + 7 = 0
0 + -1y = 3 + 7
-1y = 3 + 7
Combine like terms: 3 + 7 = 10
-1y = 10
Divide each side by '-1'.
y = -10
Hope it helps. (:

Step-by-step explanation:
Answer:
Data
Equation               25x² + 64y² = 1600
Process
1.- Divide all the equation by 1600
                             25x²/1600 + 64y²/ 1600 = 1600/1600
-Simplify
                              x²/64 + y²/ 25 = 1
2.- Equation of a horizontal ellipse
                             
3.- Find a, b and c
    a² = 64             a = 8
    b² = 25             b = 5
-Calculate c with the Pythagorean theorem
                   a² = b² + c²
-Solve for c
                   c² = a² - b²
-Substitution
                   c² = 8² - 5²
-Simplification
                  c² = 64 - 25
                  c² = 39
-Result
                  c = √13
4.- Find the center
          C = (0, 0)
5.- Find the vertices
          V1 = (-8, 0)     V2 = (8, 0)
6.- Find the foci
          F1 = (-√13, 0)   F2 = (√13, 0)
