The slope-intercept form of a line is
y=mx+b
where m is the slope
b is the y-intercept
if you convert the function into an equation, then
y=4-5x
rearranging the equation
y=-5x +4
thus
m=-5 and b=4
the y-intercept of the function is 4
You would need to know the dimensions of the pyramid and wether it was triangle or square bottomed
1 quart is equal to 4 cups so the answer is B.
