Answer:
% Apple juice = 
× Y × 100.
Step-by-step explanation:
Given:
Ratio of apple juice to water = 4 : 3 = Y i.e 4+ 3 = 7
To find the exact % of apple juice used in recipe, we use the ratio of juice to water provided, given Y as any amount of apple cider.
∴ equation × Y = amount of apple juice.
for percentage, × Y × 100 = amount of apple juice.
Proof:
In 200ml apple cider, amount of apple juice present
= 4/7 × 200 = 114.2ml of juice
To make upto 00ml cider, add (200-114.2)ml of water.

Answer:
<h2>11x - y = -79</h2>
Step-by-step explanation:
The standard form of an equation of a line:
The point-slope form of an equation of a line:
m - slope
(x₁, y₁) - point
We have the points (-7, 2) and (-8, -9). Substitute:
Convert to the standard form:
<em>use the distributive property </em>a(b + c) = ab + ac
<em>add 2 to both sides</em>
<em>subtract 11x from both sides</em>
<em>change the signs</em>
