Answer:
Slope is m=0

Step-by-step explanation:
The slope of any line that is perpendicular to the y-axis is zero.
The reason is that any line that is perpendicular to the y-axis is also parallel to the x-axis and the slope of the x-axis is zero.
The equation of any line perpendicular to the y-axis is and passes through (a,b) is y=b.
The given point is (-5,-3) hence the required equation is

The answer is 2/9 of a gallon.
Because 2/9 x 9 (people) is 2 (gallon)
