-3x - y = 5

• No solution

• (1,8)

• (-1,-3)

• (-1,-2)

• Isolate the x in the second equation so that she can substitute into the first equation.

• Solve both equations for y so that she can easily graph the equations and find the point of intersection.

• Multiply the second equation by 3 so that the x's have the same coefficient to then add the two equations together.

• Multiply the second equation by -3 so that the x's have opposite coefficients to then add the two equations together.
