will give and more points if correct please I need help The equations of four lines are given. Identify which lines are perpendicular.

Line 1: y+8x=−5

Line 2: x+16y=−5

Line 3: y=−6x−7

Line 4: y+3=18(x−1)

Lines 2 and 3 are perpendicular.

Lines 1 and 2 are perpendicular.

All four lines are perpendicular.

Lines 1 and 4 are perpendicular.

D

Step-by-step explanation:

We have the four lines:

Remember that for two lines to be perpendicular, their slopes are negative reciprocals of each other.

So, let’s determine the slope of each line.

For Line 1, we can rewrite our equation as:

So, the slope of Line 1 is -8.

We can rewrite Line 2 as:

So, the slope of Line 2 is -6.

The slope of Line 3 is also -6.

And the slope of Line 4 is 1/8.

So, the slopes of perpendicular lines must be negative reciprocals.

The negative reciprocal of -8 (slope of Line 1) is 1/8. We multiply by a negative and then take the reciprocal.

Since the slope of Line 4 is 1/8, this means that Lines 1 and 4 are perpendicular.

For Lines 2 and 3, they have the same slope, not negative reciprocals of each other.

So, they will instead of parallel instead of perpendicular.

And Line 1 is perpendicular only to Line 4, and no other line.

Therefore, our answer is D.
