Question

Plz help does the point (-1, -1) lie on the line y= 4x + 3 ?

Answer 1

Yes it does.

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)

Answer 2

yes, it does

Explanation:

point (-1, -1)

• y=4x+3

if (-1, -1) lies on this line, it will make below equation correct:

• -1=4*(-1)+3
• -1=-4+3
• -1=-1

Answer is yes
