Answer:

Yes it does.

Step-by-step explanation:

For (-1, -1) to lie on the line y= 4x + 3 ; that would mean substituting x=-1 into the expression we should be able to get y=-1 so let's test that.

Substituting x=-1 in y= 4x + 3;

we have : y= 4(-1)+ 3 = -4 +3 = -1;

Since y=-1 tallies with the point (-1, -1)
