The third one because it passes the vertical line test
Answer:
B. (1/2, 3)
Step-by-step explanation:
It is perhaps easiest to try the point values in the equations.
A — 4·2+1 = 9; -2·2 +4 ≠9 . . . . not the answer
B — 4·1/2 +1 = 3; -2·(1/2) +4 = 3 . . . . this is the answer
we need go no further since we have the answer
Answer:
Let's solve your system by substitution.
x+y=−5;2x+2y=−5
Step: Solvex+y=−5for x:
x+y=−5
x+y+−y=−5+−y(Add -y to both sides)
x=−y−5
Step: Substitute−y−5forxin2x+2y=−5:
2x+2y=−5
2(−y−5)+2y=−5
−10=−5(Simplify both sides of the equation)
−10+10=−5+10(Add 10 to both sides)
0=5
