Answer:
(4, -6)
Explanation:
Pre-Solving
We are given the following equations:
y = -2x + 2
y = -x - 2
We want to find the intersection of these two lines, which will be a point.
Solving
There is a property in math known as transitivity, which says that if a=b and b=c, then a=c.
Since both -2x + 2 and -x -2 are equal to y, this means that -2x + 2 = -x -2.
We can take this equation and use it to solve it for the x value of the point. We can start by adding 2 to both sides.
-2x + 2 = -x - 2
+ 2 +2
_____________
-2x + 4 = -x
Now, we can add 2x to both sides.
-2x + 4 = -x
+2x +2x
_____________
4 = x
So, the value of x of the point is 4.
Now, we need to find the y value.
We can substitute x as 4 in either y=-2x+2 or y=-x-2.
Taking the second equation for instance:
y = -4 - 2 = -6
The value of y of the point is -6.
The answer is (4, -6).
