Question

Solve each system of equations below by graphing, please use my graphy = 2xy = -x + 3

Answer 1

Given:

y= 2x ; y=-x+3

Substitute the value of x as -2,-1,0,1,2

y=2x

`\text{When x=-2, y=-4}`
`\text{When x=-1, y=-}2`
`\text{When x=0, y=}0`
`\text{When x=1, y=}2`
`\text{When x=2, y=}4`

y= -x+3

`\text{When x=-2, y=}5`
`\text{When x=-1, y=}4`
`\text{When x=0, y=}3`
`\text{When x=1, y=}2`
`\text{When x=2, y=}1`

Therefore, the solution is (1,2) .
