Question

y = 4x + 3 y = - 1 4 x - 5 What is the BEST description for the lines represented by the equations?

Answer 1

Answer:

D. perpendicular that's the answer

Answer 2

Answer:

Given lines are PERPENDICULAR to each other.

Step-by-step explanation:

We have the equations, $y=4x+3$ and $y=-\frac{x}{4}-5$

The slope-intercept form of a straight line is 'y=mx+b', where m is the slope and b is the y-intercept.

So, accordingly we get that,

The given equations have slopes $m=4$ and $m=\frac{-1}{4}$.

As we see that, $4\times \frac{-1}{4}=-1$

Thus, the product of the slopes of the given lines is -1.

Hence, the given lines are PERPENDICULAR to each other.
