Consider the linear system of equations. y = –x + 9 y = 0.5x – 6 What is the best viewing window to find the solution to the system of equations? 0 Less-than-or-equal-to x Less-than-or-equal-to 20, 0 Less-than-or-equal-to y Less-than-or-equal-to 20 0 Less-than-or-equal-to x Less-than-or-equal-to 20, –10 Less-than-or-equal-to y Less-than-or-equal-to 20 –20 Less-than-or-equal-to x Less-than-or-equal-to 0, –20 Less-than-or-equal-to y Less-than-or-equal-to 0 –20 Less-than-or-equal-to x Less-than-or-equal-to 0, –10 Less-than-or-equal-toy Less-than-or-equal-to 10

The correct option is 2.

2) 0 Less-than-or-equal-to x Less-than-or-equal-to 20, –10 Less-than-or-equal-to y Less-than-or-equal-to 20.

Step-by-step explanation:

We have been given 2 equations.

y = -x + 9

y = 0.5x-6

Lets graph the both equations.

From the graph we can see that the line of both equations intersect at point (10,-1)

As the value of x of solution lies in the positive x axis, it is not necessary to graph the value of negative x-axis. It terminates the options 3 and 4 given.

As the value of y of solution lies in negative y-axis, it is necessary to graph some values of negative y-axis. It terminates option 1.

The only option left is option 2
