The equations of four lines are given. Identify which lines are perpendicular. Line 1: y=2
Line 2: y=1/5x−3
Line 3: x=−4
Line 4: y+1=−5(x+2)

Line 2 and Line 4 are perpendicular

Step-by-step explanation:

Line 2: y=1/5x−3

Line 4: y+1=−5(x+2)

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

b if for most of the graph

d if y intercept
