interpreting report for cross product in regression

Question

Hello,

I have seen similar questions to mine here, but I am still a bit confused. I am doing an ordinal logistic regression using the fit model function, to compare the slopes of 3 regressions (for 3 different groups). I wish to see if the slopes of these regression lines are significantly different or not.  I have included here the two sections of the report I wish to interpret.  Can someone tell me what are the 3 slopes, and how I figure out which ones are significantly different from each other (or not) ?

thanks

Hi,

I've tried to space out the table better, although it's damn hard to copy it here from another program.  Hope someone can help. thanks

sorry, the spacing in the table is terrible
