Question

The perpendicular distance of the
point P(-3,-4) from the x-axis is
A 4
B 3
C -3
D -4​

Answer 1

Answer:

intersection between 4x+2y=7 and y-axis i.e. x=0

put x=0 in 4x+2y=7

y=7/2

hence point of inersection is (0,7/2)

now unknown equation parellel to

y-7x+5=0

slope of unknown line =slope of above line =7

now equation of line

(y-7/2)=7 (x-0)

7x-y+7/2=0

14x-2y+7=0
