The region where the values are negative lies between p₁ and p₂ ...
The p₁ < p < p₂
Answer: A
Step-by-step explanation:
We need to get this form:
we need to begin by isolating y on the left side. To do this, we must subtract 4x.
Rewrite it so that we get this form:
Since y needs to be completely isolated, divide by 4.
Divide;
