Answer:
The equation of line for given points is y = - 40 x - 42
Step-by-step explanation:
Given two points as :
( -1 , - 2 ) and ( 3 , - 162 )
Now, Equation of line in points form
y - 
= m × ( x - 
)
Where m is the slope of line
And, m = 
or, m = 
or, m = 
∴ m = - 40
So, Slope of line for given points is - 40
Now equation of line can be written as
y - ( - 2 ) = ( - 40 ) × ( x - ( - 1 ) )
or, y + 2 = ( - 40 ) × ( x + 1 )
or, y + 2 = - 40 x - 40
or, y = - 40 x - 40 - 2
∴ y = - 40 x - 42
Hence the equation of line for given points is y = - 40 x - 42 Answer

Q1
I like to use the standard form to write the equation of a perpendicular line, especially when the original equation is in that form. The perpendicular line will have the x- and y-coefficients swapped and one negated (remember this for Question 3). Thus, it will be
... 5x - 2y = 5(6) - 2(16) = -2
Solving for y (to get slope-intercept form), we find
... y = (5/2)x + 1 . . . . . matches selection C
Q2
The given equation has slope -3/6 = -1/2, so that will be the slope of the parallel line. (matches selection A)
Q3
See Q1 for an explanation. The appropriate choice is ...
... B. 4x - 3y = 5
Q4
The given line has slope -2, so you can eliminate all choices except ...
... D. -2x
Q5
The two lines have the same slope (3), but different intercepts, so they are ...
... A. parallel
