Question

Find and correct the error!

Answer 1

Explanation:

Jen 's drawing shows that the lines are parallel in fact they are not parallel ! Since their slopes are not equal !

`\displaystyle \left \{ {{y=2x+3} \atop {-y=2x+1}\ \ |\cdot (-1) } \right. => \left \{ {{y=\boldsymbol {2}x+3} \atop {y=\boldsymbol {-2}x-1}} \right. => -2\\eq 2`

They will intersect at point A with coordinates :

`2x+3=-2x-1 \\\\ 4x=4 \\\\ x=-1 \ ; \ y=1 => A(-1 \ ; \ 1)`
