What is the graph of the system y = –2x + 3 and 2x + 4y = –8?
What is the graph of the system y = –2x + 3 and 2x + 4y = –8?
y = -2x + 3
2x + 4y = -8
4y = -2x -8
y = -2x/4 - 8/4
y = -1/2 x - 2
y = -2(1.5) + 3 = -3 + 3 = 0
y = -1/2 (0) -2 = 0 - 2 = -2
Based on my computation, it's the first graph. https://us-static.zdn.net/files/d01/7d6001f27a4a81b0644c0bfba32ec50a.gif
The graph of the two system of equation is the first graph and has been attached as image in this solution.
y = –2x + 3 --- (1)
2x + 4y = –8 --- (2)
substitute the value of y into (2)
2x + 4(-2x + 3) = -8
2x -8x + 12 = -8
-6x = -20
x = -20/6
x = 3.33
From (1), y intercept = 3
From(2), y intercept = -2
4y = -8 + 2x
y = -2 + 1/2x
Thus, the graph of the two system of equation is the first graph and has been attached as image in this solution.
