Step-by-step explanation:
Answer:
y = 8x
Step-by-step explanation:
Since slope is 8/1 which is equal to 8 and x-intercept is 0.
Put these in slope-intercept equation i.e y = mx + b
The answer is going to be 5162.
Answer:
≈ 10.63
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = P(- 1, - 1) and (x₂, y₂ ) = L(6, - 9)
d = 
= 
= 
=
=
≈ 10.63 ( to the nearest hundredth )
