Answer:
Slope = undefined.
Step-by-step explanation:
A vertical line always has an undefined slope.
The slope-intercept form of the equation of a line is
y = mx + b,
where
m = slope and b = y-intercept.
The point (0, 3) is the y-intercept, so b = 3.
The slope is -2, so m = -2.
y = mx + b
y = -2x + 3
