The slope is -0.2
Without an equality sign it is not an equation but when a straight line equation is parallel to another straight line the slope remains the same but the y intercept is different
x = -3 represents a vertical line whose slope is undefined.
There is no "equals" sign therefore "x-9" is NOT an equation.

That of course will depend entirely on the straight line equation which has not been given but in general in the equation y = mx+b the slope is m and b is the y intercept
A line with no slope is a vertical line. The slope is undefined, and cannot be represented by a real number. A horizontal line has a slope, but the slope is zero. Consider the "y = mx + b" form of the straight line equation. For a horizontal line the slope is zero, so y = 0x +b => y = b, which is the equation of a horizontal line. For a vertical line, there is no slope, so you can't substitute for m; the equation can't be written in the form y = mx +b. The equation of a vertical line has the form x = a.
The equation, y = -4x - 3, is written in what's called slope-intercept form. The general equation for slope-intercept form is y = mx + b, where m is the slope of the line, and b is the y-intercept. So, for the equation in question, m = -4 and b = -3. Thus, the slope of the line is -4.
