We can see that the equation has a slope and a y-intercept .
Since parallel lines have equal slopes, this means that we know that the slope of the unknown parallel line is .
Now let's use the point slope formula to find the equation of the parallel line by plugging in the slope and the coordinates of the given point
.
Start with the point slope formula
Plug in , , and
Rewrite as
Distribute
Multiply
Subtract 6 from both sides.
Combine like terms.
So the equation of the line parallel to that goes through the point
is .
Here's a graph to visually verify our answer:
Graph of the original equation (red) and the parallel line (green) through the point
