Answer:
The equation of line with slope
and points ( - 1 , 3 ) is y =
x +
Step-by-step explanation:
Given equation of a line as :
y =
x + 3
The line equation is in the form of y = m x + c
Where m is the slope of the line
Now while comparing given line equation with standard line equation ,
So , slope of the line m =
∵ Another line is passing through points ( - 1 , 3 ) , and is parallel to given line
Now <u>if two lines are parallel then slope of both lines are equal </u>
Let The slope of another line = M
So, M = m =
∴ The equation of line with slope
and passing through points ( - 1 , 3 ) is
y -
= M × ( x -
)
Or, y - 3 = ×
( x + 1 )
or, 4 × ( y - 3 ) = 5 × ( x + 1 )
Or, 4 y - 12 = 5 x + 5
Or, 4 y = 5 x + 17
∴ y =
x +
Hence The equation of line with slope
and points ( - 1 , 3 ) is y =
x +
Answer
The general formula for the equation of the straight line is:
y−b=m(x−a) where
m is the slope
a is the x coordinate of the given point
b is the y coordinate of the given point
The slope is given as 2
x coordinate in the given point is 5
y coordinate of the given point is 9
Substitute with these values in the mentioned equation as follows:
y−9=2(x-5)
-4-6= -10
-10 = Y
-4 = X
Therefore the answer is (-4,-10) which isn’t on the options
