Question

Solve the system of linear equations by graphing. Round the solution to the nearest tenth.

y = –0.25x + 4.7
y = 4.9x – 1.64
The approximate solution to the system is (, ).
)

Answer 1

The approximate solution to the system is (1.2, 4.4).

Explanation:

Answer 2

we have

`y=-0.25x+4.7`

`y=4.9x-1.64`

we know that

The intersection both graphs is the solution of the system of equations

using a graphing tool

see the attached figure

The solution is the point
`(1.2,4.4)`

therefore

the answer is

The approximate solution to the system is
`(1.2,4.4)`
