Answer

$y=3x-1$

Work Step by Step

Target: $y=mx+b,$ (find m and b). Slope: Our line has the same slope as the given line since they are parallel. Rewrite the given line in slope-intercept form. $6x-2y=11\qquad/-6x$ $-2y=-6y+11\qquad/\div(-2)$ $y=3x-\displaystyle \frac{11}{2}$ the slope we are after is $m=3$ Intercept: The form of our linear equation is $y=3x+b$ To find b, substitute the coordinates of the given point and solve for b. $0=3(\displaystyle \frac{1}{3})+b$ $0=1+b\qquad/-1$ $-1=b$ Thus, $y=3x-1$
