Nikita plotted 4 points on the grid below which equation represents the relationship between the x values and the y values of the plotted points

Find the volume of the largest rectangular box in the first octant with three faces in the coordinate planes and one vertex in the plane x + 2y + 3z = 15.

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Aline has a slope of negative 1/4 the past two points -5/4 and 1 what is the equation of the line
