Which of the following statements is true about the system
2x + y = 4
x - y = 2
A. There is an order pair (2,0) that satisfies both equation
B. There are infinitely many ordered pair that satisfy both
equations
C. The slope o the first equation is equal to the slope of the
second equation
D. The slope and the y - intercept of the first equation and
second equation are equal.
2x + y = 4
if y = 0
y = mx + b
y = -2x + 4
0 = - 2(x) + 4
x = 2
x intercept = (2, 0)
x - y = 2
y = mx + b
y = x - 2
if y = 0
0 = x - 2
x = 2
x intercept = (2, 0)
Both equations have an order pair of (2, 0) that satisfies the equation
Answer:
There is an order pair (2,0) that satisfies both equation
