Which of the following equations best represents the line segment AB? y = -3x + 2 y = -2x + 1 y = -3x - 2 y = -2x - 1

OpenStudy (darkigloo):

do you know what the y intercept of that graph is?

OpenStudy (anonymous):

No..

OpenStudy (darkigloo):

the y intercept is where the function crosses the y axis. Now can you tell me where it is?

OpenStudy (anonymous):

Is the y intercept 2?

OpenStudy (darkigloo):

yes :) now the equation of a line is y=mx+b right?

OpenStudy (anonymous):

Right

OpenStudy (darkigloo):

b = y intercept.

OpenStudy (anonymous):

So its the first one right?

OpenStudy (darkigloo):

yup.

OpenStudy (anonymous):

Thank you
