Answer
$$y=3x+5$$
Work Step by Step
$$y = 3x - 1$$
This equation is in the form $y=mx+b$ with $m$ as slobe and $b$ as y-intercept. Since parallel lines have the same slope, then the equation we are looking for will have a slope=$3$.
Thus, we have:
$$y = 3x +b$$
We can now use the given point $(-1,2)$ to find the y-intercept, $b$.
$$y = 3x +b$$ $$2 = 3(-1) +b$$ $$2 = -3 +b$$
Add $3$ to both sides:
$$2+3 = -3+3 +b$$ $$5=b$$
The equation will now become:
$$y=3x+5$$
Plotting both equations will give us:
