Then we took the equation y=1/2x - 1 and substituted it for y in the equation 2x+y=4 . You're new equation would be 2x+1/2x - 1 = 4. You combine the X's to get 2.5x-1=4, then add 1 to each side to get 2.5x=5. Next you divide 2.5 from 5 to get X=2. then replace X in the equation 2x+y=4 with 2 to get 2(2)+y=4 . You  get 4+y=4, subtract 4 and you get y=0. So your solution to the equation in (2, 0).  


using graphing to solve our problem, you first change each equation into slope intercept form. then take the equation Y=1/2x-1 and graph it by putting a point at -1 and going up 1 over 2 each time. then take the equation y=-2x+4 and put point at positive 4 then go down 2 over 1. those two equation meet at (2, 0). ]]> 2016-12-14 18:51:00 UTC https://padlet.com/pontiousl/9erlt6ffzx4f/wish/143696926 https://padlet.com/pontiousl/9erlt6ffzx4f/wish/143696930 Ashton and Karissa

First we had to change 2x+y=4 into y-intercept form which was y=-2x+4. Now scene they both equal y, make them equal each other ( 1/2x -1=-2x=4). Then solve for x to get 2. After that substitute 2 for x in ONE of the equations, solve for y. Then your answer is (2,0). When you graph, put equations  in y-intercept form. Graph both equations and the solution is the only point the two lines intersect which is (2,0).

Next we drew our line down. After we put our point at negative 1 and went up 1 over to the right 2 times and drew our line. Last we found the point that both of the lines met at and it was (2,0). For substitution, we plugged in 1/2x-1 into 2x+y=4. We got 2x+1/2x-1. We simplified it to 5/2x-1=4. Add 1 to 4 then to get x by itself, we multiplied 2/5 to both sides. 5 times 2/5 equals 2. Plug 2 back in for x to get y. 1/2(2)-1=0. 1-1 =0. Y is 0. (2,0). ]]> 2016-12-14 18:51:46 UTC https://padlet.com/pontiousl/9erlt6ffzx4f/wish/143697217 https://padlet.com/pontiousl/9erlt6ffzx4f/wish/143697546 First, change the equation 2x+y=4 into slope-intercept form by subtracting 2x on both sides of the equaion. This will equal y=-2x+4.
Then, plot the y intercept of the first equation on the graph (4). Since the slope is -2, you have to go down 2 and over 1. After that, graph the second equation. Plot the y intercept on the same graph and go up 1 over 2. Both lines will intersect at (2,0). This is your solution. ]]> 2016-12-14 18:52:38 UTC https://padlet.com/pontiousl/9erlt6ffzx4f/wish/143697546 https://padlet.com/pontiousl/9erlt6ffzx4f/wish/143697774 We started by changing the equation into slope intercept form ( y= -2x + 4).  We then graphed to get the solution (2,0).  

Substitution : Use substitution to substitute, 1/2x into 2x+y=4. Solve. Then  plug in answer for x. Solve, to get solution (2,0).

We first took the first bee´s path and started at y=4. Then, we went down 2, over to the right 1 until we hit the x-axis. Afterward, we took the second bee´s path and started at y=-1. Then, we went up 1, over to the right 2 until we hit the x-axis again. The bee hive was at (2 , 0), where the bees meet.

Part E:
We used substitution to prove our answer. First, we took 1/2x-1 and plugged it into 2x+y=4, the result was 2x+1/2x-1=4. If you evaluate the equation, the answer will be x=2. Then, we took x=2 and plugged it back into y=1/2x-1, the result was y=1/2(2)-1. If you evaluate the equation, the answer will be y=0.
