Answer:
y = - 2x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1,1) ← 2 points on the line
m = = - 2
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = - 2x + 3 ← equation of line
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
