Interpreting an unstandardized partial regression coefficient

#1
Hi, anyone know what two equivalent interpretations of the below unstandardized partial regression is?

Y^MathsValue = -7.31-0.27XAnxiety + 0.52XSelfCon + 0.09XM_Attitude + 0.15XF_Attitude

where the DV is Perceived Value of Maths (MATHSVALUE) and the four IVs are Maths Anxiety (ANXIETY), Mathematical Self-Confidence (SELFCON), Attitudes of Mother (M_ATTITUDE), and Attitudes of Father (F_ATTITUDE).

I have written this, but I am confused about the minus sign in front of the -7.31:


The partial regression coefficient for Anxiety indicates that, for a unit decrease in scores on Anxiety, we expect scores on the Y^MathsValue to decrease by 0.27 units, holding constant scores on Mathematical Self-Confidence (SelfCon), Attitudes of Mother (M_Attitude), and Attitudes of Father (F_Attitude).

Likewise, The partial regression coefficient for Anxiety indicates that, for a unit increase in scores on Anxiety, we expect scores on the Y^MathsValue to increase by 0.27 units, holding constant scores on Mathematical Self-Confidence (SelfCon), Attitudes of Mother (M_Attitude), and Attitudes of Father (F_Attitude).

Any help would be most appreciated!
