(3y-5 + 2y)*2 = (5y-5)*2 = 10y-10
Answer:
-10=x1 -17=y1
-8=x2 -15.7=y2
formula:
y2 -y1
_____ =m
x2-x1
y1=m(x1)+b
Step-by-step explanation:
Hey.
The answer is (7,4).
The change of x is -6. Divide that by two(=-3) and add it to the first x-coord and you get 7.
Do the same for your y-value(change =+6/2= +3) and you'll get 4.
