keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above
so we're really looking for the equation of a line whose slope is 2 and it passes through (-1 , 3)
now, to graph a line, we only need two points and connect them through, well, hell we already have (-1 , 3), let's get another hmmm
say if x = 2
y = 2(2) + 5 => y = 9
that gives us the 2nd point of (2 , 9)
Check the picture below.
