I believe the answer is A.
The other values have repeated X values.
Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.
Let's change 0.02 into a percentage.
This means that every year, her investment will earn a <em>2% simple interest.</em>
Assuming the equation is: 4x + 2y = 12 , we can rearrange it in slope- intercept form to:
y = -2x + 6
which has the slope = -2.
So the correct choice is b.
