Question

How do you solve this system , y=1/2x-4 and y=-2x+1 by graphing

Answer 1

x=2

y=-3

Explanation:

we have

`y=(1)/(2)x-4` ----> equation A

`y=-2x+1` ----> equation B

Solve the system by graphing

Remember that the solution of the system of equations by graphing is the intersection point both lines.

using a graphing tool

The intersection point is (2,-3)

therefore

The solution is

x=2

y=-3
