Use the point slope formula. then, substitute the values inside the formula.
x1 =3
y1= -2
m = 23
y -y1 = m ( x - x1)
y - (-2) = 23 (x - 3)
y + 2 = 23 ( x - 3)
x1 =3
y1= -2
m = 23
y -y1 = m ( x - x1)
y - (-2) = 23 (x - 3)
y + 2 = 23 ( x - 3)
We are asked to sum the two trinomials 
. We can start by using the distributive property to remove the parenthesis, giving us 
. Next, when we combine like terms, we get
