Y = x + 5 [y=mx+b; so m=1]
Parallel lines have the same slope, so the equation of the line looks like:
y = x + b and we need a point to determine b. Use (3,2):
2 = 3 + b
-1 = b
The equation of the parallel line is: y = x - 1

A plane in th Cartesian Coordinate system has two axes: x and y. The x axis usually plots the value of the independent variable and the y axis usually plots the value of the dependent variable. That's why an equation of the form y=x-1 gets an input value for x and produces an output value for y. For this equation, every input value for x is reduced by 1 to get the output value for y. Points are listed as (x,y). Here are some points on the graph of y=x-1: (5,4) (2,1) (-5,-6) (0,-1) When x=0 that is the y-intercept. The equation m=x-1 is in the slope-intercept form of the equation of a line. It looks like y=mx+b where m is the slope and the point (0,b) is the y-intercept.
