Graphing is good to graph a line. Substitution is good because you have to subtitute the value whichis easy and elimination is good just to find oone variable first and the other variable

Alisha Levy · Answer 2

Graphing is a good method when you have small integers or fractions as your slope.

Substitution is a good method when you have two equations, and when one of the coefficient of the variables is one.

Linear combinations is a good method when you have the same coefficient for the same variable in 2 different equations.
