Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 
x + 4 ← is i slope- intercept form
with slope m = -
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 2 + c ⇒ c = 5 + 2 = 7
y = - x + 7 ← equation of parallel line
Answer:
B(2,3),C(2,-3)
Step-by-step explanation:
On y-axis symmetry有手就行
11x + 2 = 13x, 9x - 4 = 5x, 5x + 13x = 18x
Answer: D:
To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
