Answer:
Step-by-step explanation:
Slope = m = -3/7
[tex]y=\dfrac{-3}{7}x+3\\\\\\Substitute \ y =6 \ and \ find \ the value \ of x\\\\6=\dfrac{-3}{7}x+3\\\\\\6-3=\dfrac{-3}{7}x\\\\\\3=\dfrac{-3}{7}x\\\\\\3*\dfrac{7}{-3}=x\\\\\\x=-7[/tex]
A(-7,6)
[tex]Substitute \ x=9 \ and \ find \ value \ of y\\\\y=\dfrac{-3}{7}*9+3\\\\\\y=\dfrac{-27}{7}+3\\\\\\Multiply \ the \ entire \ eaution \ by \ 7\\\\7y =7*\dfrac{-27}{7}+7*3\\\\\\7y=-27+21\\\\7y=-6\\\\ y =\dfrac{-6}{7}[/tex]
B(9 , -6/7)
