Help its math!! please don't ignore 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)

Step-by-step explanation:

First find the slope of the lines. If any two lines have a slope which is the negative reciprocal of each other then they're perpendicular

That is if two slopes m1×m2=-1 then m1=-1/m2 and m2#=-1/m1

Line 1 has slope -8

line 2 has slope -1/16

line 2 has slope -6

line 2 has slope 18

It appears none of the lines are perpendicular
