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?
and if that point isn't in the answer choices, then test the other two.
you would see if 3,-2 is on A or if -1, 0 is on line A
Neither of those points are on line A.
So where do they intersect?
You do know how to read a graph, correct?
yes i thinks its C
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
Why do you think it's C?
because i thought it made since lol
I almost gave you the answer.
I did tell you that B and C are NOT the right answer.
Those say that those points are on line A, but not line B, but neither of those points are on line A.
Come on, think right, don't just guess
i didnt see that sorry
is it A or D?
and tell me why
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.
but look at the graph
oh ok so A
is it going 1 to the right from 0 or 2 to the right?
noooo, you just said A. It's D. But WHY is it D?
no i just said D lol my typing is off my bad
ohhhhh gotcha that's good then!
