Answer:
We calculate the slop of a line.
How to find the slope:
Pick any two points on a graph
The formula of slope is 
For example we have two points that contains the coordinates (5,2) (7,4)
Inserting them to the formula would result in:

=
Our rate of change is rise 2, run 2.
Answer:

Step-by-step explanation:
given,
angular deceleration, α = -0.5 rad/s²
final angular velocity,ω_f = 0 rad/s
angular position, θ = 6.1 rad
angular position at 3.9 s = ?
now, Calculating the initial angular speed




now, angular position calculation at t=3.9 s



Hence, the angular position of the wheel after 3.9 s is equal to 5.83 rad.
An odd or far from average result on a graph or chart is called an outlier.
Answer:
-3
Step-by-step explanation:
this is x equals to -3
we can divide the 4 to other side
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
x = 5 x = 4
