Because they have the same inclination so if we try to draw them on a diagram they will be parallel to each other.
Answer:
y-5=-2(x+3)
Step-by-step explanation:
y-y1=m(x-x1)
m=-2
y-5=-2(x-(-3))
y-5=-2(x+3)

Answer: (2,2)
Step-by-step explanation:
I'm going to use substitution to solve this:
First, I use the second equation to solve for y in terms of x.
2x - y = 2
-y = 2 - 2x
y = 2x - 2
Then, I plug the value for y into the first equation:
2x + 4y = 12
2x + 4(2x - 2) = 12
2x + 8x - 8 = 12
10x - 8 = 12
10x = 20
x = 2
Now that we have x, we can plug it into either equation (I used the first) to get the value for y:
2x + 4y = 12
2(2) + 4y = 12
4 + 4y = 12
4y = 8
y = 2
We get the point (2,2) as a solution.
Note: This is the point where both lines intersect.
If the store decreases its prices by 20%, then ur actually paying 80%
0.80(120) <=== ur expression
lets check..
0.80(120) = 96
120 - 0.2(120) = 120 - 24 = 96 (yep, it matches)
