Question

Find the point slope equation of the line containing -3,-4 and having slope m=2

Answer 1

Y=mx+b
So -4=(2)(-3)+b
-4=-6+b
+6 +6
2=b
The answer would be y=2x+2

Answer 2

your initial equation would be y=mx+b  

So, what you would have to do, is plug in your numbers: -4=(2)(-3)+b

-4=-6+b

+6 +6

2=b  

your final answer would be y=2x+2
