Best ResponseYou've already chosen the best response.0you need two x's and y's value to find slope so when line is horizontal y values would be the same for y_2 y_1 so when we subtract same number what would we get ?

Best ResponseYou've already chosen the best response.0so when we substitute x's nd y's for their values \[\frac{ 33 }{ 21}=slope\]
