Question

Q5. The line x+5=0 is parallel to y axis. State true or false.​

Answer 1

Answer:

$false.$

Step-by-step explanation:

slope of line parallel to Y-axis is 1/0

Here , equation of lines are

x - 7y + 5 = 0------------(1)

3x + y = 0 ----------------(2)

solve equations (1) and (2) for finding point of intersection of these two lines .

x - 7y + 5 + 21x + 7y = 0

22x + 5 = 0

x = -5/22 , put it in equation (2)

y = -3x = 15/22

hence, the point is ( -5/22, 15/22)

Equation of required line by using

y - y1 = m(x - x1)

(y - 15/22) = 1/0(x + 5/22)

0 = x + 5/22

22x + 5 = 0

Therefore, required line: 22x + 5 = 0

Answer 2

Answer:

yes

Step-by-step explanation:

because x+5=0 and x=-5 and it is parallel to y-axis
