1. Where does the graph of y = x+2 intersect the x-axis?
A (0, 2)
B (0, -2)
C (-2, 0)
D (2,0)

C (-2, 0)

Step-by-step explanation:

y = x+2

intersect the x-axis when y = 0, then

0 = x+2

x = -2

astronomers is your final answer! : )

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
