Question

Express y in terms of x , given that 2x-5y=7. check wheather the point (-3, -2) is on the given line.

Answer 1

 2x - 5y = 7

5y = 2 x - 7
y = (2 x - 7 ) / 5 

check if (-3, --2)  lies on the line:  substitute  x = -3 in the equation

y = (2 *-3 - 7 )/5 = -13/5    Hence  at x = -3,  y = -13/5 but not -2. so  (-3,-2) is not on the line.
