for that two lines be parallel the condition is that two slope be equal m1 = m2

Now you must calculate with point givens both slope , with the following formula

m= y2-y1/ x2-x1, for the firsts two points P( -7,0) and Q( 6,-5)

m = -5-0/6-(-7) , m = -5/13

for the seconds points R (-1,-1) and S( 0,-4)

m = -4-(-1)/ 0-(-1) = -3/1 = -3

the lines are not parallel, m1 ≠ m2
