Answer:
y=-3x-7
Step-by-step explanation:
y=mx+b , m represents slope, b represents y intercept
a)219.8
b)3846.5
a) circumference is pi*diameter, so 3.14*70 is 219.8
b) area is pir^2, and radius is 1/2 of diameter, it would be 3.14*35^2, so 3.14*1225, so 3,846.5 in^2.
slope=(y2-y1)/(x2-x1)
where (x1,y1)=(-7,-6)
(X2,y2)=(5,-6)
slope=(-6+6)/(5+7)=0
50 percent
The equation is C = 65h
