Question

find the equation of a straight line passing through the intersection of 2 X + 5 Y - 4 is equal to zero with x-axis and parallel to the line 3x - 7 Y + 8 is equals to zero​

Answer 1

Answer:

3x-7y-6=0

Step-by-step explanation:

2x+5y-4=0.............(i)

equation of x axis is y=0;(remember it,on x axis the y coordinate of any point is 0,hence y=0)

put the value of y=0 in (i)

=>2x=4

=>x=2

=>point of intersection is(2,0)...................(ii)

now,

by principle of family of lines(you would have studied or will study in 11th/12th)

required equation of line is 3x-7y+c=0................(iii)

putting (ii) in (iii)

=>6-0+c=0

=>c=-6

Hence the required equation of line is 3x-7y-6=0

Answer 2

Answer:

3x-7y-6=0

Hope this helps you!
