Answer:
y = -2x + 3
Step-by-step explanation:
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Being m the slope and (h,k) is a point through which the line passes.
We are given the point (0,3) and the slope m=-2
Substituting:
y - 3= -2 ( x - 0 )
Operating:
y - 3= -2x + 0
y - 3= -2x
Adding 3:
y = -2x + 3
