Question

Graph the equations to solve the system

y=-x

y=2x+3

click on the correct answer #1 solutions :all numbers on the line #2 no solutions {} #3 one solution:{-1,1} #4 one solution:{0,3}

Answer 1

This system has one solution (-1,1)

Explanation:

The attached picture shows the solutions for the system

If we equalize the eq. obtain the following

-x=2x+3

From we obtain that x= -1

Using the first equation y=-x, we obtain that y=1

so (-1,1)
