2 answers:
Answer:
option (b) is correct.
Step-by-step explanation:
Given : the equation
We have to plot the graph for the given equation and choose the correct graph
Since the general equation of circle is given as,
Where (h, k) is the center of the equation and r is the radius.
Thus, for the given equation
on comparing we have h = -8 , k = 1 , r = 3
Thus, the graph will be a circle with center at (-8, 1) and radius 3 .
Thus, the graph in option (b) is correct.

Answer:
Option B and C are correct.
are the expression incorrect for slope
Step-by-step explanation:
Slope is defined as the change in the dependent variable relative to the change in the dependent variable
or the ratio of the horizontal changes to vertical changes between any two points on the graph of the line.
The vertical changes between any two points is rise
The horizontal changes between any two points is run.
Formula for slope is given by:
For any two points and
then slope is:
or we can write this as:
Δy =
Δx =
⇒
Therefore, the expression which are incorrect for slope are;
