Answer:
15 unit
Step-by-step explanation:
Applying
/RT/ = √[(y₂-y₁)²+(x₂-x₁)²]............. Equation 1
Where /RT/ = distance between point R and Point T
From the question,
Given: y₁ = -9, x₁ = 8, y₂ = -9, x₂ = -7
Substitute these values into equation 1
/RT/ = √[(-9-(-9))²+(-7-8)²]
/RT/ = √[(0)²+(-15)²]
/RT/ = √225
/RT/ = 15 unit
Hence the distance between point R and point T is 15 unit
