Question 229237
SOLVE BY GRAPHING.


2X+Y=5
3X-Y=10


Step 1.  The graph of these two lines is shown.


{{{graph(600, 600, -10, 10, -10, 10, -2x+5, 3x-10)}}}


Step 2.  Based on the graph the intersection point is 


Step 3.  ANSWER:  The intersection is {3,-1)


As a check, let's do the above by substitution


*[invoke linear_substitution "x", "y", 2, 1, 5, 3, -1, 10 ]


Which yields the same results.


I hope the above steps were helpful.
