1. Which description best describes the solution to the following system of equations?

y = –x + 4
y = 3x + 3 (4 points)


Line y = –x + 4 intersects the line y = 3x + 3.
Lines y = –x + 4 and y = 3x + 3 intersect the x-axis.
Lines y = –x + 4 and y = 3x + 3 intersect the y-axis.
Line y = –x + 4 intersects the origin.

2.
A pair of equations is shown below.

x + y = 5
y = 1/2(one half) x + 2

If the two equations are graphed, at what point do the lines representing the two equations intersect? (4 points)


(2, 5)
(5, 2)
(2, 3)
(3, 2)

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.

question 3

Answer: D infinity many solutions

Step-by-step explanation:

when two lines overlap each other their values are the same therefore their always correct, so the answer is infinity many solutions
