Question

Decide whether the lines are parallel, perpendicular or neither.

x + 4y = 7 and 4x – y = 3​

Answer 1

Answer:

hiiii

your answer is here !

Step-by-step explanation:

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
