The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
The new line is parallel to y = 2x - 5 ... because parallel lines have the same slope, the slope of the new line is m = 2.
Then we're given b = 1/3, so putting it all together yields
y = 2x + 1/3 for the slope-intercept form
