Given points: (9,2) & (10,-5)
where
Via Slope-Point Form,
, answer
*If you want to see the graph, let's check the intercepts.
Via Slope-Intercept Form,
Thru point (9,2):
---> , y-Intercept
Another point (10,-5),(should be the same):
---> , y-Intercept
We let Fy=0, to get x-Intercept:
---->
, x-Intercept
Therefore, your Line Eqn ----> y=-7x+65
Having
From y-Intercept (0,65):
Next point,
X:
Y:
(1,58)
Next point,
X:
Y:
(2,51)
Next point,
X:
Y:
(3,44)
You can do the other points, and from what we gathered we'll see the graph,
----> Slope in GREEN dots
Thank you,
Jojo
