Answer:
The equation of line is y = 3 x +18
Step-by-step explanation:
Given as :
The points are
(,
) = (- 9, -9)
(,
) = (- 6 , 0)
Let The slope = m
Now,<u> The slope is calculated in points form</u>
So, Slope =
I.e m =
or, m =
or, m =
I.e m = 3
So, The slope of points = m = 3
<u>Now, the equation of line in slope - point form can be written as</u>
y - = m ( x -
)
where m is the slope of line
i.e y - (-9) = ( 3 ) × ( x - (-9) )
or, y + 9 = 3 × (x + 9)
∴ y + 9 = 3 x + 27
Or, y = 3 x + 27 - 9
O,r y = 3 x + 18
So, The equation of line is y = 3 x + 18
Hence, The equation of line is y = 3 x +18 . Answer
