The graph shows two lines, A and B. 

A coordinate plane is shown. Two lines are graphed. Line A has the equation y equals x minus 1. Line B has equation y equals negative 3 x plus 7.  

Based on the graph, which statement is correct about the solution to the system of equations for lines A and B?

 (1, 2) is the solution to both lines A and B.
 (−1, 0) is the solution to line A but not to line B.
 (3, −2) is the solution to line A but not to line B.
 (2, 1) is the solution to both lines A and B.

what do you think? this is the easiest one. A solution to equations is where they intersect, or the point at which they touch. Look at the graph. Where are they touching?

whovianchick · Answer

and if that point isn't in the answer choices, then test the other two.

whovianchick · Answer

you would see if 3,-2 is on A or if -1, 0 is on line A

whovianchick · Answer

Neither of those points are on line A.

whovianchick · Answer

So where do they intersect?

whovianchick · Answer

You do know how to read a graph, correct?

nuccioreggie · Answer

yes i thinks its C

whovianchick · Answer

the first number is how many you go to the right or left from 0. If it's a positive number, you go to the right. Ex: 4,5- you go 4 to the right. If it's a negative number, you go to the left. Ex: -4,5 you go to the left 4

The second number is going up and down. Positive is up, negative is down

whovianchick · Answer

Why do you think it's C?

nuccioreggie · Answer

because i thought it made since lol

whovianchick · Answer

I almost gave you the answer.

whovianchick · Answer

I did tell you that B and C are NOT the right answer.

whovianchick · Answer

Those say that those points are on line A, but not line B, but neither of those points are on line A.

whovianchick · Answer

Come on, think right, don't just guess

nuccioreggie · Answer

i didnt see that sorry

whovianchick · Answer

is it A or D?

whovianchick · Answer

and tell me why

nuccioreggie · Answer

a because the first number is how many you go to the right or left from 0. If it's a positive number, you go to the right.

whovianchick · Answer

you're close

whovianchick · Answer

but look at the graph

nuccioreggie · Answer

oh ok so A

whovianchick · Answer

is it going 1 to the right from 0 or 2 to the right?

whovianchick · Answer

noooo, you just said A. It's D. But WHY is it D?

nuccioreggie · Answer

no i just said D lol my typing is off my bad

whovianchick · Answer

ohhhhh gotcha that's good then!
