sin(θ) = ⁻⁴/₅
sin⁻¹[sin(θ)] = sin⁻¹(⁻⁴/₅)
θ ≈ -53.13

tan(θ) > 0
tan(53.13) > 0

Answer:

A' ( 2, 4) and B' ( -4, 0)

Step-by-step explanation:

A ( -2, 4) and B( 4,0) reflected over the y-axis

A' ( 2, 4) and B' ( -4, 0)

3) show that the two lines with the given slopes are parallel, perpendicular neither. My₁ = 3/4 M₂ = 12/16 . solve it by showing

Jet001 [13]

Parallel lines have equal slope so

M1-M2=0

Lets check

M1=3/4
M2=12/16=3/4

Now

M1-M2
3/4-3/4
0

Lines are parallel
