Find the slope of the line passing through the points (7, 7) and (7, -8) find the slope of the line passing through the points (-6, 7) and (9, 7)

Respuesta :

Step-by-step explanation:

to work out gradient

change in y ÷ change in x

first lines gradient

(7 - - 8) ÷ (7 - 7) = 0

second lines gradient

(7 - 7) ÷ (9 - - 6) = 0
