a,ve do thi ham so y=3x

b,tim toa do diem A , biet A thuoc do thi ham so tren va A co tung do la 6

c,tim diem tren do thi sao cho diem do co tung do va hoanh do bang nhau

Cho do thi ham so y=ax² va diem M{2:2}

a] Tim a biet do thi {P} cua ham so di qua diem M va ve do thi {P}

b] Ve do thi [d] cua ham so : y-2x-2 tren cung mat phang toa do tren. Tim toa do giao diem cua 2 do thi tren bang phuong phap dai so

cho ham so y=ax+b                                                          xac dinh a va b de duong thang (d):y=ax+b cat truc tung tai diem co tung do bang -2 va cat do thi (P) noi tren tai diem co hoanh do bang 2

a,ve do thi cac ham so y=\(\frac{-3}{2}\)x va y=\(\frac{2}{3}\)x tren cung 1 he truc toa do

b,tren do thi ham so y=\(\frac{-3}{2}\)x lay diem A co hoanh do la 2.tren do thi ham so y=\(\frac{2}{3}\)x.Lay diem C co hoanh do la 3.do goc AOC,sau do bieu dien diem B tren mat phang toa do sao cho OABC la hinh vuong

y=(3m-2)x -2m

a> Xac dinh m tai diem co hoanh do =2

b> Xac dinh m de do thi ham so cat truc tung tai diem co tung do =2

c> Xac dinh toa do giao diem cua 2 do thi vs m tim duoc o 2 cau a va b

choham so y= (2m-1)x+m-3          (d)

a,Tim m de do thi ham so cat truc hoanh tai diem co hoanh do x=\(\sqrt{2}\)-1

b, Tim m de (d) cat (d1):y=x+5 tai diem tren truc tung

a,ve do thi ham so y=\(\dfrac{-3}{2}\)x và y=\(\dfrac{2}{3}\)x tren cung 1 he trục toa do

b,tren do thi ham so y=\(\dfrac{-3}{2}\)x lay diem A co hoanh do la 2 ,Tren do thi ham so y=\(\dfrac{2}{3}\)x,lay diem C co hoanh do la 3.Đo goc AOC,sao do bieu dien B tren mat phang toa do sao cho OABC la hinh vuong

Gia su A va B la hai diem thuoc do thi ham so y=3x+1

a, tung do cua A bang bao nhieu neu hoanh do cua no bang 2/3

b, hoanh do cua B bang bao nhieu neu tung do cua no bang _8

cho ham so y=x+4

a) cho A(1;3); B(-1;3) ; C(-2;2) ;D(0;6) diem nao thuoc do thi ham so

b) cho diem M , N co hoanh do 2;4. xac dinh toa do diem M,N
