Using the given points, determine the delta symbol y. (-3,-5) and (0,10)

Δy = 15

Step-by-step explanation:

Δy represents the change in the y-coordinates

We are given points (-3,-5) and (0,10)

here y₁ = -5 and y₂ = 10

so, delta y will be

Δy = y₂ - y₁

Δy = 10 -(-5)

Δy = 10 + 5

Δy = 15

So, delta y Δy =15

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
