For this case we have that by definition, the point-slope equation of a line is given by:

Where:
m: It's the slope
It is a point through which the line passes
According to the statement data we have:

Substituting we have:

By law of signs of multiplication we have to:

Answer:
The requested equation is: 
Step-by-step explanation:
x + y = 3 ---------------- eqn 1
y = -6x + 3 ------------- eqn 2
Substitute y for -6x + 3 in equation 1
x + -6x + 3 = 3
x - 6x + 3 = 3
-5x + 3 = 3
Collect like terms
-5x = 3 - 3
-5x = 0
Divide both sides by -5
x = 0
