文章:線性函式通常以 f ((x) = ax + b 的形式寫成. a表示直線的梯度,它給出了依賴變數的變化速率. 這也被稱為"斜率". 代表y軸的交點. 它是依賴變數 y 的值,換句話說,當 x = 0 時, 例如,我們有一個函式 f (x) = x + 5. 這是一個標準形式的線性函式. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/8\/85\/Do-Linear-Functions-Step-1Bullet1-Version-2.jpg\/v4-460px-Do-Linear-Functions-Step-1Bullet1-Version-2.jpg","Urbigl":"\/images\/thumb\/8\/85\/Do-Linear-Functions-Step-1Bullet1-Version-2.aid-2.jpg\/4531126-v4-728px-Do-Linear-Functions-Step-1Bullet1-Version-2.jpg","Wsmallth":40,"smallHeight":345,"Wbigth"Crediv:"bigth"728","Height:"46","5","<div class="parent-parent-parent-levels" class="parent-levels" class="parent-levels" class="parent-levels">" class="parent-level 總的來說,你應該找到三個點, 檢查準確性. 在上面的例子中,您可以選擇使用 -1,0和1作為x值. 解決如圖所示. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/7b\/Do-Linear-Functions-Step-2Bullet1-Version-2.jpg\/v4-460px-Do-Linear-Functions-Step-2Bullet1-Version-2.jpg","bigUrl":"\/images\/thumb/7\/7b\/Do-Linear-Functions-Step-2Bullet1-Version-2.jpg\/aid4531126-v4-728px-Do-Linear-Functions-Step-2Bullet1-Version-2.jpg","smallWidth":460,"smallHeight":45,"Wbigth"/7\/7b\/bigHeight":"46","5","<div"div"=n"parserver-output"\n"\n"\n"<br/a>"<p>你得到了<br/p><br/p><p><br/ 在上面的示例中,你的圖形會看起來像這樣. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/f\/f2\/Do-Linear-Functions-Step-3Bullet1-Version-2.jpg\/v4-460px-Do-Linear-Functions-Step-3Bullet1-Version-2.jpg","bigUrl":"\/images\/thumb\/f\/f2\/Do-Linear-Functions-Step-3Bullet1-Version-2.jpg\/aid/4531126-v428-7px-Do-Linear-Functions-Step-3Bullet1-Version-2.jpg","smallthumb":460,"CreativeHeight:345,"bigthumb"Wid28",""Height7","46","creativeHeight5","creativeHeight"46","parent-saving-Step-3Bullet1-Version-2.jpg","\\\/\n\n 使用一個線條將它們連線成一條直線. 如果圖中沒有三個點在同一條直線上, 那麼你在某個地方犯了一個錯誤. 回去再計算一次. 在上面的示例中,你的圖形會看起來像這樣. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/2\/25\/Do-Linear-Functions-Step-4Bullet1-Version-2.jpg\/v4-460px-Do-Linear-Functions-Step-4Bullet1-Version-2.jpg","bigUrl":"\/images\/thumb\/2\/25\/Do-Linear-Functions-Step-4Bullet1-Versionjpg\/aid4531126-v4-728px-Do-Linear-Functions-Step-4Bullet1-Version-2.jpg","smallWth":40,"smallHeight":35,"bigWth":45",bigWth:"28",""Height7","46","5","parent":"parent":"parent":"parent":"parent":"parent"<p><br/><br/><br/><p>  什麼是總結?
識別線性函式的標準形式. 找到至少兩個點. 繪製出這些點. 連線這些點.
