的函数解析式；（2）根据题意和（1）中的函数关系式，可以求得两车相遇的时间；（3）根据题意，可以求得出租车为提前25分钟与客车相遇，应将速度提高为每小时多少千米．【详解】解：（1）由图象可得，客车的速度为：600÷10＝60（千米/小时），出租车的速度为：600÷6＝100（千米/小时），设客车的解析式为：1y kx =，把点（10，600）代入，则60010k =， ∴60k =，∴y 1关于x 的函数关系式为y 1＝60x ；设出租车的解析式为2y ax b =+，把点（0，600）和（6，0）代入，则60060b a b =⎧⎨+=⎩， ∴100600a b =-⎧⎨=⎩，∴y 2关于x 的函数关系式为y 2＝﹣100x+600；故答案为：60，100；y 1＝60x ，y 2＝﹣100x+600；（2）令60x ＝﹣100x+600，解得x ＝154，即154时两车相遇；（3）∵154时＝3小时45分钟，出租车提前25分钟与客车相遇， ∴出租车出发的时间为3小时20分钟，∵3小时20分钟＝133小时，∴出租车的速度为：600÷133﹣60＝120（千米/小时），即出租车为提前25分钟与客车相遇，应将速度提高为每小时120千米．【点睛】本题考查一次函数的应用，解答本题的关键是明确题意，利用一次函数的性质和数形结合的思想解答． 22．（1）1364y x =-+，21y 12x =+；（2）15；（3）存在，理由见解析．【分析】（1）直接把点A （0，6）代入l 1解析式中，求出m 的值；把点B （-2，0）代入直线l 2，求出k 的值即可；（2）首先求出点C 的坐标，然后求出点D 坐标，进而根据S △ABD =S △ACB +S △ACB 求出答案；（3）分点P 在点B 的左边和右边两种情况进行讨论，利用三角形面积公式求出点P 的坐标．【详解】解：(1)∵直线113:4l y x m =-+与y 轴交于A (0,6)， ∴m =6， ∴1364y x =-+，∵22:1l y kx =+分别与x 轴交于点B (−2,0)， ∴−2k +1=0， ∴k =12， ∴21y 12x =+； (2)令21y 12x =+中x =0，求出y =1， ∴点C 坐标为(0,1)，联立364112y x y x ⎧=-+⎪⎪⎨⎪=+⎪⎩ ，解得x =4，y =3 ∴点D 的坐标为(4,3)， ∴11(61)2522ACB S AC BO =⨯=⨯-⨯=△ 154102ACD S =⨯⨯=△∴51015ABD ACD ACD S S S =+=+=△△△； (3)设点P 坐标为(m ,0)，当点P 在B 点的右侧时， BP =m +2，114(2)615223ABP S BP AO m =⨯=⨯+⨯=⨯△，解得m =143，则点P 坐标为(143，0)，当点P 在B 点的左侧时， BP =−2−m ，114(2)615223ABP S BP AO m =⨯=⨯--⨯=⨯△，解得m =−263，则点P 坐标为(−263，0)，综上点P 的坐标为(143，0)或(−263，0)．【点睛】本题考查了一次函数综合题的知识，本题涉及到求一次函数解析式、两直线交点问题，三角形面积等知识，解本题（2）的关键是求出D 点的坐标，解答（3）的关键是进行分类讨论．23．（1）1-；3；（2）△ABM 的面积为2m -；（3）点P 的坐标为10,2⎛⎫ ⎪⎝⎭或70,2⎛⎫- ⎪⎝⎭．【分析】（1）根据非负数性质可得a 、b 的值；（2）根据三角形面积公式列式整理即可；（3）先根据（2）计算S △ABM ，再分两种情况：当点P 在y 轴正半轴上时、当点P 在y 轴负半轴上时，利用割补法表示出S △BMP ，根据S △BMP =S △ABM 列方程求解可得．【详解】解：（1）∵|1|30a b ++-=， ∴10a +=，30b -=， ∴1a =-，3b =；（2）如图1所示，过M 作ME x ⊥轴于E ， ∵(1,0)A -，(3,0)B ， ∴1OA =，3OB =， ∴4AB =，∵在第三象限内有一点(2,)M m -， ∴||ME m m ==-， ∴114()222ABMSAB ME m m =⨯=⨯⨯-=-．（3）设(0,)P n ，BM 交y 轴于点C ，连接MP ，BP 如下图：设直线BM 的解析式为y kx b =+，把(3,0)B ，52,2M ⎛⎫--⎪⎝⎭代入得 30522k b k b +=⎧⎪⎨-+=-⎪⎩，解之得：1232k b ⎧=⎪⎪⎨⎪=-⎪⎩，即1322y x =-， ∴30,2C ⎛⎫- ⎪⎝⎭，当52m =-时，11545222ABMm S AB y =⋅=⨯⨯=． ∵BMPABMS S=，∴()1||52x x B M PC -=，即13(32)522n ⨯++=，解之得：12n =或72n =-，综上，点P 的坐标为10,2⎛⎫ ⎪⎝⎭或70,2⎛⎫- ⎪⎝⎭．【点睛】本题主要考查了非负数的性质，坐标与图形的性质，利用待定系数法求一次函数解析式，利用割补法表示出△BMP 的面积等知识，根据题意建立方程是解题的关键． 24．（1）70，95；（2）3570y x =-；（3）1.2 2.8t ≤≤或4.67t ≤≤．【分析】（1）根据图象结合题意，即可得出A 、B 两点之间的距离是70m ．设甲机器人前2min 的速度为xm/min ，根据2分钟甲追上乙列出方程，即可求解；（2）先求出F 点的坐标，再设线段EF 所在直线的函数解析式为y ＝kx ＋b ，将()2,0E 、()3,35F 两点的坐标代入，利用待定系数法即可求解；（3）设()0,70D ，()2,0E ，根据图象可知两机器人相距28m 时有三个时刻（0～2，2～3，4～7）分别求出DE 所在直线的解析式、GH 所在直线的解析式，再令28y

=+，将()2,0E ，()3,35F 代入，得20335k b k b +=⎧⎨+=⎩，解得3570k b '=⎧⎨=-⎩，则线段EF 所在直线的函数解析式为：3570y x =-．（3）如图：设()0,70D ，()7,0H ， ∵()0,70D ，()2,0E ，∴线段DE 所在直线的函数解析式为：3570y x =-+，()4,35G ，()7,0H ，∴线段GH 所在直线的函数解析式为：3524533y x =-+，设两机器人出发min t 时相距28m ，由题意得：357028t -+=或357028t -=，或352452833t -+=，解得： 1.2t =或28t =.或 4.6t =，1.22.8t ∴≤≤或4.67t ≤≤时，两机器人相距不超过28m ．【分析】本题考查一次函数的应用，解答本题的关键是明确题意，找出所求问题需要的条件，利用一次函数的性质和数形结合的思想解答．25．（1）34k =；（2）()918804S x x =+-<<；（3）16,23⎛⎫- ⎪⎝⎭或642,93⎛⎫-⎪⎝⎭ 【分析】（1）把点E 的坐标()8,0-代入直线6y kx =+，即可求得答案；（2）根据三角形的面积公式列出解析式，根据题意求出自变量x
