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

Hi Bianca :)
Step-by-step explanation:
Answer:
D) x=-3, y=-7
Step-by-step explanation:
9x - 7y = 22
x + 3y= -24
9x - 7y = 22
x= -24-3y
9(-24-3y)-7y=22
x= -24-3y
-216-27y-7y=22
x= -24-3y
-34y=22+216
x= -24-3y
-34y=238
x= -24-3y
y=238/(-34)
x=-24-3y
y=-7
x=-24-3*(-7)
y=-7
x=-24+21
y=-7
x=-3
(x,y)=(-3,-7)
