Answer:
use a calculator
Step-by-step explanation:
Find the slope first:
m=y2-y-1/x2-x1
m=2-10/-3-1
m= -8/-4
m= 2
Select a point & put into y=mx+b to find b.
y=mx +b
10 =2(1) + b
10 =2 +b
8 = b
Rewrite the equation with your slope &intercept:
y=2x + 8
That's ^ the equation that describes your line!
The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
