I WILL GIVE BRAINLIEST!!! PLZ HELP ASAP!!!
Fed [463]

Answer:

C

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = E(- 2, 2) and (x₂, y₂ ) = F(4, - 6)

EF = \sqrt{(4+2)^2+(-6-2)^2}

    = \sqrt{6^2+(-8)^2}

    = \sqrt{36+64}

    = \sqrt{100} = 10 → C

Write the equation of the line that passes through the given points:
Airida [17]

Answer:

y+1=5/2(x+2)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-6-(-1))/(-4-(-2))

m=(-6+1)/(-4+2)

m=-5/-2

m=5/2

y-y1=m(x-x1)

y-(-1)=5/2(x-(-2))

y+1=5/2(x+2)
