✌️_______UR ANSWER_______✌️

$<u>Solutions$

x + 4y = 7

4y = -x + 7

y = (-1/4) x + 7 

Slope of the equation x + 4y = 7 is -1/4.

Again, 4x – y = 3

y = 4x – 3

Slope of the equation 4x – y = 3 is 4.

Since multiplying both the slope of the equation = -1/4 × 4 = -1

Therefore, the given two equations are perpendicular to each other.

Answer- Perpendicular

Answer 2

Answer-:

x+4y =7

4y= -x+7

y= (-1/4)x+7

Slope of the equation x+4y = 7 is (-1/14)

Again 4x-y= 3

y= 4x-3

Slope the equation 4x-y = 3 is 4

Since multiplying both the slop of equation = -1/4×4= -1

There for the given two equations are perpendicular each other.

So the answer is Perpendicular.....☺️

Be brainly.....☺️
