Sorry i'm asking a lot of questions i just dont understand

answer:

incorrect

step-by-step explanation:

to calculate the distance (d) use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 5)

d =

    =

    = = = = 5 ← exact value

answer:

6y -8

step-by-step explanation:

8y-2(y+4)

distribute the 2

8y -2y -8

combine like terms

6y -8

answer:

undefined

step-by-step explanation:

the slope is found by using the formula

the points are (1,4) and (1,-3)

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

    = (-3-4)/ (1-1)

    = -7/ 0

when we divide by 0 the answer is undefined
