Systems of linear equations: Mixed exercises
Mixed exercises: Step 1/3
A linear equation with two variables, #x# and #y#, has the general form
\[ \ell :a\cdot x + b\cdot y = c\] where #a\neq 0#, #b\neq 0#, and #c# are constants.
Instead of thinking of #a#, #b#, and #c# as constants, we can think of them as parameters, #p#, #q#, and #r#. That way, we can see the general form as a three-parameter family of linear equations with two variables,
\[ \ell _{p,q,r}: p\cdot x + q\cdot y = r \]
Isolate #y# in the equation #\ell _{2, -6, 8}#. Simplify your answer.
