Question 1022398
{{{system(y=-x/2+1/2,y=2x-4)}}}, the same system.


{{{graph(300,300,-5,5,-5,5,-x/2+1/2,2x-4)}}}
This graph might be distorted, but appears to show intersection about  (2,-1/2).


Solving can start algebraically by equating the two formulas for y.
{{{-x/2+1/2=2x-4}}}
{{{-x+1=4x-8}}}
{{{1=5x-8}}}
{{{5x=9}}}
{{{x=9/5=1&4/5}}}
THIS SHOULD SUGGEST THAT THE INTERSECTION POINT ON THE GRAPH IS NOT DISTORTED.    The x-coordinate is actually a little less than 2, being {{{x=1&4/5}}}.  The point is a little difficult to read on the graph.


Continue with algebra to find the y-coordinate to help understand what you see on graph.  {{{y=2x-4=2(9/5)-4=18/5-4=18/5-20/5=-2/5}}}, simply {{{y=-2/5}}}.


Maybe you can find this clearer on paper, but intersection is  ( 9/5, -2/5 ).
