Answer:
≈ 7.07
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 7, - 2)
d = 
= 
= 
= 
≈ 7.07
Answer:
Step-by-step explanation:
The rate of change is measured by the slope of the line in this linear table.
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 0) and (x₂, y₂ ) = (3, 2) ← 2 ordered pairs from the table
m = 
= 
= ← rate of change

Hope I helped!:)</span></span></span></span>
Just isolate the variable x.
x*5+3=2
5x=-1
x=-1/5
Step-by-step explanation:
only attached the displacement/time graph
