Ineed a teacher or someone who knows how to solve equation really good..

B

Step-by-step explanation:

An absolute value equation has the form y= a|x-h|+k where (-h,k) is the vertex or point of the absolute value graph. This graph has vertex (3,1) and is facing downward so a is negative. This means only b and d are options since they have a -2 in front. Since the vertex is (3,1) this would be (-3,1) in the equation. The equation is y=-2|x-3| +1.
