Solve the system by graphing. Select the solution(s).<br> y = x + 2<br> y = 0.5(x + 2)

faltersainse [42]

Answer:

Part 1) The solution is the point (-2,0)

Part 2) The solutions are the points (-2,0) and (0,2)

Step-by-step explanation:

Part 1

we have

$y=x+2$ -----> equation A

$y=0.5(x+2)$ ----> $y=0.5x+1$ ---> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both graphs

using a graphing tool

The solution is the point (-2,0)

see the attached figure N 1

Part 2

we have

$y=x+2$ -----> equation A

$y=0.5(x+2)^2$ ----> equation B

Solve the system by graphing

Remember that the solution of the system are the intersection points both graphs
