Yes you do! In fact not just I. You move al l three down right after or before you move the units to the right.
Point slope formula: y-y1=m(x-x1). Answer: y-7=6(x-(-4))
It could be -20.50 but not sure do u have answer choices
I hope this helps you
1)
x= -2y
2. (-2y)+4y=0
0=0
2)
x+2x= -3
x=-1
y= -2
3)
7x+2x+2=4
9x=2
x=2/9
y=2/9+1
y=11/9
