Answer 1

Answer:

To find four solutions , we will substitute x with any real number and calculate y value:

when x= 1 ==> y=-3(1)-6 = -3-6=-9. Or the pair (1,-9) is a solution.

When x= 2 ==> y= -3(2)-6= -12. or the pair (2,-12) is a solution.

When x= -3 ==> y=-3(-3)-6 = 3. ...

When x= -2 ==> y= -3(-2)-6= 0\
