Answer
The equation is $y=-\dfrac{3}{2}x+2$
Work Step by Step
You are given $(2,-1)$ which is parallel to the equation $y=-\dfrac{3}{2}x+6$.Find the equation of the points:
The lines are parallel so they have the same slope so $y=-\dfrac{3}{2}x+b$, plug in the points into the equation to find b.
$y=-\dfrac{3}{2}x+b$
$-1=-3+b$
$b=2$
The equation is $y=-\dfrac{3}{2}x+2$
