Answer 1

1) y=-1

2) y=kx+b

$left { {{3=2k+b} atop {5=-2k+b}} right. \8=2b\b=4\3=2k+4\-2k=1\k=-0,5$

y=-0,5x+4

3) y=1

4) y=kx+b

$left { {{1=2k+b} atop {0=4k+b}} right. \left { {{-2=-4k+-2b} atop {0=4k+b}} right. \-2=-b\b=2\0=4k+2\4k=-2\k=-0,5$

y=-0,5x+2

5) x=-3

6) y=kx+b

$left { {{0=2k+b} atop {1=4k+b}} right. \left { {{0=-4k-2b} atop {1=4k+b}} right.\-b=1\b=-1\0=2k-1\2k=1\k=0,5$

y=0,5x-1

7) y=kx+b

$left { {{2=-1k+b} atop {0=1k+b}} right. \2b=2\b=1\0=1k+1\k=-1$

y=-1x+1

8) y=-4

9) y=kx+b

$left { {{2=4k+b} atop {3=0k+b}} right. \b=3\2=4k+3\-4k=1\k=-0,25$

$y=-0,25x+3$
