Formula for the slope of a line, given two points on that line slope = m=(y2y1)(x2x1)
Substituting the known values for this problem and simplifying 7/9=(3y)(0(9))
79=(3y)9
Cross-multiplying and solving
63=279y
7=3y
4=y
y=4

This question has to do with binary star systems, where 'i' is the angle of inclination of the system.
Calculate the mean expectation value of the factor sin3 i, i.e., the mean value it would have among an ensemble of binaries with random inclinations. Find the masses of the two stars, if sin3 i has its mean value.
Hint: In spherical coordinates, (θ,ϕ), integrate over the solid angle of a sphere where the observer is in the direction of the z-axis, with each solid angle element weighted by sin3θ.
