Question 71978: Which of the following is an equation of a line the passes through the point (-4, -2) and has a slope of 3

Answer:y + 2 = 3(x + 4)
I put into solver and was given a different answer. Can you show the work to arrive at problem?
Thanks

You can put this solution on YOUR website!
A SLOPE OF 3 AND PASSING THROUGH (-4,-2) IS
Y=3X+b NOW SUBSTITUTE THE POINT VALUES FOR X & Y & SOLVE FOR THE Y INTERCEPT(b)
-2=3*-4+b
-2=-12+b
b=-2+12
b=10 THUS THE EQUATION IS
Y=3X+10
---------------------------------------------
YOUR ANSWER IS CORRECT BUT IN A DIFFERENT FORM
Y+2=3(X+4)
Y+2=3X+12
Y=3X+12-2
Y=3X+10 WHICH IS THE SAME AS MY ANSWER.
