Question

Solve the following system of equations graphically. y - 4 = 0 2x - y - 2 = 0 What is the solution set? {(-3, -4)} {(-3, 4)} {(3, 4)}

Answer 1

the solution set is 3,4

Answer 2

the solution is the point
`(3,4)`

Explanation:

we have

`y-4=0` ------> equation A

`2x-y-2=0` ------> equation B

we know that

Th solution of the system of equations graphically is the intersection point both graphs

Using a graphing tool

see the attached figure

the solution is the point
`(3,4)`
