Hi,         

Determining whether the graphs of the two lines are parallel

Note:  Parallel Lines have the same slope

Using the standard slope-intercept form for an equation of a line y = mx + b 

where m is the slope and b the y-intercept.  

y + 5 = 2x   OR  y = 2x - 5    m = 2

3x - y = -5  OR  y = 3x + 5    m = 3

These two lines do not the same slope, they are not parallell lines.
