X= 2 , y= -3 
You have to multiply the second equation by a negative and the you'll get,        -3x-y=-3. the y's cancel out and then you combine the x's and the 5 and the 3 and then x=2 and then you pick one of the two equations and sub in the x and solve for y.

Determine the equation of the line shown in the graph: graph of a vertical line with an x intercept of 3
Nastasia [14]

Answer:
