Step-by-step explanation:
6x-7y=22
6x(-1)-7y=22
-6-7y=22
-7y=22+6
-7y=28
y=-4
Answer:

Step-by-step explanation:
The slope formula is 
Here,
is -6,
is 4,
is -5, and
is 4.


So, the slope of the line passing through the points (-6,-5) and (4,4) is
.
Answer:
20
Step-by-step explanation:
The circumference of a circle is calculated through the equation,
C = 2πr
where C is circumference and r is radius. For this item, I assume that 12 in is the radius such that,
C = 2π(12 in) = 24π
Thus, the circumference of the circle is 24π inches.
