Question

Consider the following pair of equations:

−x − y = −5
y = x + 1

If the two equations are graphed, at what point do the lines representing the two equations intersect?

(−2, 3)

(3, −2)

(2, 3)

(3, 2)

Answer 1

-x - y = -5
y = x + 1

-x -(x +1) = -5
-x -x -1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2

y = x + 1
y = 2 + 1
y = 3
