Given: two points (3,7) and (-5,-8)
Using these points, we can find the slope of the line passing through them.
m=%287-%28-8%29%29%2F%283-%28-5%29%29=15%2F8
Using the point slope form of the line y-k=m(x-h) where (h,k) is on the line, the equation of the line is
y-3=15/8(x-7)
---
If (-33,-2/3) is on the line, it must satisfy the equation.
---
(-2/3)-3=15/8(-33-7)
(-2/3)-3=15/8(-40)
(-2/3)-3=15(-5)
(-2/3)-(9/3)=-45
-11/3=-45
---
This is a false statement, so the point (-33,-2/3) is not on the line.
