Which is the equation of the line?

OpenStudy (anonymous):

ok. let me look at the graph again

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

A. 3x + y = 9 B. 3x – y = 9 C. x – y = 9 D. x + 3y = 9

OpenStudy (anonymous):

If you do not have any attachment the only answer you can get from me is y=mx+c where m is the gradient of the line and c the y-intercept

OpenStudy (anonymous):

y2-y1/x2-x1

OpenStudy (anonymous):

points are (0,9) and (3,0)

OpenStudy (anonymous):

so 0-9/3-0

OpenStudy (anonymous):

-9/3= -3

OpenStudy (anonymous):

Thats ur slope

OpenStudy (anonymous):

ok thanks
