You can
put this solution on YOUR website!Directions say to Graph the linear System and estimate the solution. Then Check the solution algebraically. the problem is:
2x+y=13
5x-2y=1.
please break it down to to step by step on how to graph and estimate the solution.
----------------
Write each equation in slope-intercept form to get:
y = -2x+13
y = (5/2)x -(1/2)
-------------------------
Graph the two lines and estimate the solution:
--------------------------
Your estimate might be (3,4)
--------------------------
Check that solution in each of the equations:
4 = -2*3+13 = -6+13 = 7 ; you would need to adjust your estimate.---------------
---
4 = (5/2)3 - (1/2) = 7.5-0.5 = 7 ; you would need to adjust your extimate.
---
The actual solution is (3,7)
If you had estimated the solution to be (3,7) the checking process
would have shown you were correct.
