Step 1 :First, we find the slope of the given line. The slope of a line in the form \(ax+by=c\) is \(-a/b\). So, the slope of the given line is \(-8/4=-2\).
Step 2 :Since parallel lines have the same slope, the slope of the line we are looking for is also \(-2\).
Step 3 :Next, we use the point-slope form of a line, which is \(y-y_1=m(x-x_1)\), where \((x_1, y_1)\) is a point on the line and \(m\) is the slope. We substitute \((-5,-3)\) for \((x_1, y_1)\) and \(-2\) for \(m\).
Step 4 :Finally, we simplify the equation to the form \(y=mx+b\).
Step 5 :\(m = -2\)
Step 6 :\(eq = y + 3 = -2*x - 10\)
Step 7 :\(sol = -2*x - 13\)
Step 8 :\(\boxed{y=-2x-13}\) is the final answer.
