algebra 1 unit 7: systems of equations and inequalities

We are asked to find which graph represents the solution of the given system of equations:

and

We find the intersection point of the two equations by solving these system of equations using elimination method as:

subtract equation (2) from equation (1) to obtain:

Also putting this value of x in equation (1) we get:

Hence, the intersection point is:  (0.75,1.25).

Hence the graph that represents the solution of the system of given linear equations is attached to the answer.
