Hi

the standard slope-intercept form for an equation of a line is 

y+=+highlight_green%28m%29x+%2B+highlight%28b%29  

what is the slope of a line perpendicular to the line whose equation is: 

 x - y = -3    

 x = y -3     |Solve for y

 x + 3 = y    |coefficient of x = 1

    m = 1 

Perpendicular Lines have slopes that are negative reciprocals of one another

    m = -1  the slope of a line perpendicular
