Slope of the line J
(6-1) / (-3-(-6))
5 / 3
so
m = 5/3
If this line passes through (15,-1)
y = mx + c
-1 = (5/3)*15 + c
-1 = 25 + c
c = -26
equation is
y = (5/3)x - 26
Answer:
C
Step-by-step explanation:
Recall the equation for a circle:
, where the center is (h,k) and the radius is r.
The given equation is:

Another way to write this is:

Thus, we can see that h=-5 and k=-7.
The center is at (-5, -7).
Answer:
Step-by-step explanation:
One pair of coordinates is sufficient to work out the constant of proportionality.
<u>Equation in general form:</u>
and
<u>Substitute x- and y- coordinates into equation and find the value of k:</u>
Answer:
3
Step-by-step explanation:
Given that:
Integers : x, x + 1, x + 2
6x - 2(x + 1) = (x+2) + 5
6x - 2x - 2 = x + 2 + 5
4x - 2 = x + 7
4x - x = 7 + 2
3x = 9
x = 9/3
x = 3
First integer = x = 3
2nd integer = x + 1 = 3+1 = 4
3rd Integer = x + 1 + 1 = 3 + 2 = 5
Answer:
Undefined slope.
Step-by-step explanation:
The formula should be y2 - y1 over x2 - x1
Points ( 20,-16 ) and ( 19, -16 )
So ( -16 - ( -16 ) ) over ( 19 - 20 )
0 over -1
The slope is 0. Undefined.
