-1/3x
<h2>Step-by-step explanation:</h2><h3>Known :</h3>We can find the straight line equation using this formula,
Insert all we know inside the formula,
Use cross multiplication,
3(y - 1) = -1(x + 3)\
3y - 3 = -x - 3
3y = -x - 3 + 3
3y = -x
y = -1/3x
<h3>Conclusion :</h3>The correct equation is y = -1/3x
Answer:
Eva's age is 44 years
Step-by-step explanation:
Let
x ----> Brita's age
y ----> Eva's age

The sum or their ages 118
so
----> equation A
The difference in age between Brita and her daughter Eva is 30 years
so
----> equation B

Adds equation A and equation B
<em>Find the value of y</em>
substitute the value of x in any equation
therefore
Eva's age is 44 years
