Question

Please Help

Consider the following system of equations.


-2x+5y=19

y= -5/6x - 1/6


Use this graph of the system to approximate its solution.

Answer 1

x=-3.216 and y=2.514

Explanation:

We plot the graphs of the equations:

-2x+5y=19

y= -5/6x - 1/6

The point of intersection of two graphs is the solution.

On seeing the graph we see that the solution is:

x=-3.216 and y=2.514

-13/4=-3.2 and 5/2=2.5

Hence, correct option is:

B
