Дана линейная функция y =2/3+6х Найдите хочу, если у=1, у=-1, у=-2/3, у=5
1. Y=1:
1 = 2/3 + 6x
6x = 1-2/3
6x=1/3
x = 1/3*1/6 = 1/18
2. Y=-1
-1=2/3+6x
6x=-1-2/3
6x=-5/3
x=-5/3*1/6=-5/18
3, Y = -2/3
-2/3 = 2/3+6x
6x = -2/3-2/3
6x=-4/3
x = -4/3*1/6 = -4/18 = -2/9
4. Y = 5
5 = 2/3 + 6x
6x = 5-2/3
6x = 13/3
x = 13/3 * 1/6 = 13/18
