Same sign- <span> keep the </span>same sign<span> and </span>add<span> the absolute value of each number.
different signs- </span><span>keep the </span>sign<span> of the number with the largest absolute value and subtract the smallest absolute value from the largest.</span>
In this problem why is the easiest to substitute.
Just set the equations equal to each other because they both equal y
-x + 4 = 2x - 8
(You want to get all the x's to one side so add x to each side)
4 = 3x - 8
(next add 8 to both sides)
12 = 3x
(lastly divide 3 from both sides)
4 = x
You have got your x so now it is time to find that y just replace x to either of the two equations
y = 2(4) -8 or y = -(4) + 4
y = 8 - 8 y = 0
y = 0
Final Answer: y=0, x=4
1. slope= 1 work- 6-5 1
--- = - = 1
-2-3 1
4. slope= -3 work- -3- -3=-6 -3
---------- = ---- = -3
6-4= 2 1
