Answer:
A.2x + 4y = 4
-3x - y = -1
D.2x + 4y = 4
7x - y = -1
Explanation:
Given system of equations,
2x + 4y = 4 ------(1)
-5x + 5y = 5 -----(2)
x-intercept and y-intercepts of equation (1) are (2, 0) and (0, 1)
While, x-intercepts and y-intercepts of equation (2) are (-1, 0) and (0, 1)
Thus, by plotting these lines on the graph,
We get,
The intersection point of line (1) and (2) is ( 0, 1)
That is, the solution would be (0, 1),
Similarly,
Graphing -3x - y = -1, 7x + 5y = -1, 7x - y = 5 and 7x - y = -1,
We get,
A. The solution of 2x + 4y = 4, -3x - y = -1 is ( 0, 1 )
B. The solution of 2x + 4y = 4, 7x + 5y = -1 is ( -1.333, -1.667 )
C. The solution of 2x + 4y = 4, 7x - y = 5 is ( 0.8, 0.6)
D. The solution of 2x + 4y = 4, -7x - y = -1 is ( 0, 1 )
