Total volume of the glass:

40 cm³ ÷ 2/15= 40 cm³ × 15/2= 300 cm³

Indicate the equation of the given line in standard form, in the equation box below.

Illusion [34]

Perpendicular lines have slopes that are negative reciprocals of each other, so the equation of the line in point-slope form is:

$y-4=-\frac{5}{2}(x+3)$

Rewriting this in standard form,

$2y-8=-5(x+3) \\ \\ 2y-8=-5x-15 \\ \\ \boxed{5x+2y=-7}$
