A system of two linear equations has one solution. One of the equations is y = 2x + 25. Which could be the other equation? A y =
1 answer:
Answer:
B. y = -2x-25 These lines will intersect
Step-by-step explanation:
<u>y = 2x+25</u> Which line has one solution to this equation:
A. y = 2x+25 [This is the same line! The solutions are infinite.]
<u>B. y = -2x-25 </u> <u>[These lines will intersect. They'll meet at the corner of -12.5th and Zero streets (-12.5,0)]</u>
C. y = 2x-25 [Same slope, 2. They, also, will never meet. Pity]
D. y = 2x [OMG. Didn't parallel lines ever get the message. Get with the slope and focus on the bliss of intersection.]
===============
[Extra Credit]
y = 2x + 25
y = –2x – 25
-----------
y = 2x + 25
<u>y = -2x - 25</u>
2y = 0
y = 0
--
y = 2x + 25
0 = 2x + 25
2x = -25
x = -12.5
<em>The single solution is (-12.5,0)</em>

Well, parallel lines have the same exact slope, so hmmm what's the slope of the one that runs through <span>(0, −3) and (2, 3)?

so, we're really looking for a line whose slope is 3, and runs through -1, -1
