Y should also be halved.
For example, if x=4 and y=2, x=2y.
If x is halved for x=2, you get 2=2y, or y=1, which is still one half of x, so the proportion remains the same.

Answer: " r = a + b - s " .
_____________________________________________________
Step-by-step explanation:
_____________________________________________________
Given:
a + b = s + r ; Solve for: "r" ; that is; rewrite the equation in terms of: " r " .
_____________________________________________________
Subtract "s" from each side of the equation;
to isolate "r" on one side of the equation:
_____________________________________________________
→ a + b - s = s + r - s ;
→ to get:
→ a + b - s = r ;
____________________________________________________
↔ " r = a + b - s " .
____________________________________________________
→ which is the answer.

Answer:
The equation is y = -5x - 1.
Step-by-step explanation:
1. Find the slope using the formula. Slope = (4 + 1) / (-1 - 0) which is equal to 5 / -1 which is -5.
2. Use the slope-point formula to construct an equation. The equation is y - 4 = -5 * (x + 1)
3. Simplify. We would get y = -5x - 5 + 4, which is y = -5x - 1.
Answer: The equation is y = -5x - 1.
