Answer:
Slope -intercept for of equation 1: 
Slope -intercept for of equation 2: 
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
Step-by-step explanation:
We need to write equations in slope-intercept form.
The general formula of slope-intercept form is:
where m is slope and b is y-intercept.
The first equation is:

Slope-intercept form:

The second equation is: 
Rearranging: 
Slope-intercept form:

Slope -intercept for of equation 1: 
Slope -intercept for of equation 2: 
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
They have different y-intercepts.
Answer:
(x + 4)^2 + (y-9)^2 = 121
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k) ^2 = r^2 where (h,k) is the center and r is the radius
(x - -4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 121
-2,2 is the answer i think
Step-by-step explanation:
x2-x-12<0
x2-x<12
x=12
