please make sure you express it so i can verify and understand it; thank you

Suppose that a demand function is linear , that is , ` = m - up for DEP _ , where in and i are positive constants . Show that E = 1 at the midpoint of the demand curve on the interval 0 = PE _ .` . that is , at p = ]m- 1 2 17 )Select the correct formula for Elasticity E .OA . E = - P. `dadobpOB . E = _ _ .apOC .
