Why’d is the distance between(14,-16) and (-7,-16) on a coordinate plane?

Answer 1

Distance: 21

Steps:

Distance (d) = √(-7 - 14)2 + (-16 - -16)2

= √(-21)2 + (0)2

= √441

= 21

Slope and Angle:

ΔX = -7 – 14 = -21

ΔY = -16 – -16 = 0

Slope (m) =

ΔY

ΔX

= 0

θ =

arctan( ΔY )

ΔX

= 0°

Equation of the line:

y = 0x – 16

When x=0, y = -16
