Answer:
(4, -5)
Step-by-step explanation:
Here we wish to identify the coordinates of the solution of the system
y = -2x + 3
y = -x - 1
One way to solve this system is to equate the two equations: y = y, so
-2x + 3 = -x - 1.
Combining like terms results in
-x + 4 = 0.
Then x must be 4. If x = 4, then y (from the second given equation) must be
y = -(4) - 1 = -5
Then the coordinates of the solution (the point of intersection of the two lines represented by the given system) are as follows:
(4, -5)
