SOLUTION: solve systems of equations by graphing
1. y = 2x -4
y = -3x+1
2. 3x - 7y = -6
x + 2y = 11
3. 2x +3y = 7
2x - 3y = y
4. 1/4x + 2y = 5
2x - y = 6

Question 201154: solve systems of equations by graphing
1. y = 2x -4
y = -3x+1
2. 3x - 7y = -6
x + 2y = 11
3. 2x +3y = 7
2x - 3y = y
4. 1/4x + 2y = 5
2x - y = 6
5. 1/2x - y = 0
1/4x +1/2y = -2

We'll do #1 and you can take care of the rest. It's all the same sequence anyway.
1)Given
, Let Fy=0
---> }
, X-Intercept
Let Fx=0:
, Y-Intercept
, Let Fy=0
--->
, X-Intercept
Let Fx=0:
, Y-Intercept
Seeing the two lines, & :
----> Point of interection (1,-2)
*Note: we can calculate the point of Intersection by equating the two eqns.
---->
, substitute in either eqn. (we use )
*Point of Intersection, (1,-2)
Thank you,
