We know that
the equation of the line in point-slope------------> <span> (y – y1) = m(x – x1)
</span>the equation of the line in slope intercept forms. -----> y =mx+b
find the slope m
point <span>(8,-2) & (7,-4).
m=(y2-y1)/(x2-x1)---------> </span>(-4+2)/(7-8)=-2/-1----------> m=2
Part A)
find the equation of the line in point-slope using <span>(8,-2)
</span>(y – y1) = m(x – x1)---------> (y-(-2)) = 2*(x – 8)-------> y+2=2x-16
<span>y=2x-16-2--------> y=2x-18
</span>Part B)
find the equation of the line in point-slope using (7,-4)
(y – y1) = m(x – x1)---------> (y-(-4)) = 2*(x – 7)-------> y+4=2x-14
y=2x-14-4--------> y=2x-18<span>
</span>Part C)
find the equation of the line in slope intercept forms
using (7,-4)
y=mx+b--------> -4=2*7+b----------> -4=14+b-----------> b=-18
then
y=2x-18
Part D)
find the equation of the line in slope intercept forms
using (8,-2)
y=mx+b--------> -2=2*8+b----------> -2=16+b-----------> b=-18
then
y=2x-18

circle a circumference is 25.13 and the area is 50.27. circle b circumference is 9.42 and the area is 7.0 7
I have no clue about part C
Answer: 5.1
Step-by-step explanation:
pythagorean theorem: a^2+b^2=c^2
c^2-b^2=a^2 (switch around some things)
(14.9)^2 - (14)^2 = x^2 (insert values) c=14.9,b=14,a=x
222.01 - 196 = x^2
26.01 = x^2
5.1 = x
