其實就咁看條curve的話,其實不可以話完全作盡是elastic or inelastic的~因為你條curve是分了三part的(正常的curve), mid-point係 unitary elastic, upper 個 mid-point 係 elastic,under 個mid-point 就是inelastic.

因為如果你話條curve is elastic 是有問題的,條curve本身不是有彈性可分,除非係extremely case, perfectly elastic or perfectly inelastic,你就可以話條curve係elastic or not.
不過如果你想畫圖容易些,可以嘗試將圖畫大些,然後按你想佢係elastic or inelastic 而去畫上半部分 or 下半部分~

不過如果你真是想粗略的看,那你跟上面位朋友便可~

希望幫到你la~~keke~

elastic 個條線比較平
(increase of P < decrease of Q)
inelastic 個條線比較直
(increase of P > decrease of Q)

prefectly 的話elastic 就係horizontal的線inelastic 就係vertical的線
