Question

SS below

Answer 1

Well, to find the \(m\) part of \(y=mx+b\), do \(\dfrac{rise}{run}\),
the \(m\) here would be \(\dfrac{3}{1}\), or just 3. And both of these are opposites, so \(m\) is \(\color{lime}{3}\) and \(\color{cyan}{-3}\).

now we have to find \(b\), to find b look at the graph and locate the points at which the lines cross the y axis, this would be \(\color{lightgreen}{6}\) and \(\color{lightblue}{-6}\)

now plug in the choices into 2 \(y=mx+b\) equations,

\(y=\color{lime}{3}x+\color{lightgreen}{6}\)
\(y=\color{cyan}{-3}x+\color{lightblue}{-6}\)

and there's your answer.

Answer 2

I generally just plug it into my graphing calculator

Answer 3

Same, just a more thorough explanation for people who don't have graphing calculators.
