1. The best answer is A since a solution is where 2 lines intersect. Whether or not they intersect the x or y axis is completely irrelevant (so is whether they intersect the origin).
2. y=-x+5
-x+5=1/2x+2
-x+3=1/2x
3=3/2x
2=x
y=-(2)+5
y=3
Answer: (2,3)
3. It seems like the lines are completely on top of each other (coinciding) so there are infinitely many solutions.
Answer:
1: 3/4 = 6/8 = 9/12
2: 2/3 = 4/6 = 6/9
3: 8/9 = 16/18 = 24/27
Step-by-step explanation:
C is correct because not all square roots are rational.
