Answer
y=$\frac{2}{3}$x
Work Step by Step
You have (0,0) parallel to y=$\frac{2}{3}$x+1.Since parallel lines have the same slope, the slope for the other line is also $\frac{2}{3}$.Use the slope and (0,0) to find the y-intercept:
y=mx+b
0=$\frac{2}{3}$(0)+b
0=0+b
0=b
There is no y-intercept so the equation would be y=$\frac{2}{3}$x.
