The slope of line pq is m= 1/4. find the equation of the line that is parallel to line pq and that has the y intercept b= -3

For this case we have that the generic equation of the line is given by:
 
 Where,
 m: slope of the line
 b: intersection with the y axis.
 Since the line is parallel to PQ, then the slopes are equal.
 We have then:
 
 On the other hand we have:
 
 Substituting values we have:
 
 
 The equation of the line that is parallel to line PQ and that has the and intercept b = -3 is:
