若点(-2,y1)和(3,y2)都在直线y=3x+5上,则下列结论正确的是( )
举一反三
- 若点(-4,y1)、(2,y2)都在直线y=-13x+12上,则y1______y2(填“>”、“=”或“<”).
- 已知点()(()-()1(),()y()1())(),()(2(),()y()2())(),()(()-()3(),()y()3())()都在函数()y()=()x()2()的图象上,则()()A.()y()1()<()y()2()<()y()3()B.()y()1()<()y()3()<()y()2()C.()y()3()<()y()2()<()y()1()D.()y()2()<()y()1()<()y()3
- 已知点(x1,y1)和(x2,y2)都在直线y=34x-1上,若x1<x2,则y1______y2.
- 若x=[1 2 3 4 5];y=[2 -1 4 3 -2];则z=x.*y=()
- 已知x=1,y=2,z=3,执行下列语句if(x>y) z=x;x=y;y=z;则x,y,z的值分别是 A: x=1,y=2,z=3 B: x=2,y=3,z=1 C: x=2,y=2,z=1 D: x=2,y=3,z=3
