#### Answer

$y=-9x-6$

#### Work Step by Step

You are given $2.4=-3.6x-0.4y$.
To easily graph, you want to get $y$ all by itself on the left of the equals sign so that the equation will resemble $y=mx+b$.
You can start to do this by adding $0.4y$ to both sides of the equation:
$2.4+0.4y=-3.6x$.
Next, subtract $2.4$ from both sides:
$0.4y=-3.6x-2.4$.
Now, Simply divide everything by $0.4$ to isolate $y$:
$y=-9x-6$.
Since your equation is now in $y=mx+b$ format, it will be easy to graph.
Your y-intercept is $b=-6$.
Your slope is $m =-9$ meaning your next point will be 9 down the y axis and 1 to the right along the x axis from the previous point.
