7.1 Distance, Mid-Point, and Circles

We will remember the distance and the mid-point formulas and learn about the equations for circles.

Multiple Choice

Find the distance on a number line between the points $-9.3$ and  $10.6$ .

•  $0.65$  

•  $1.3$  

•  $19.9$  

Multiple Choice

Find the standard form equation for the circle with center $\left(1,\ 2\right)$ and radius  $5$ .

•  $\left(x-1\right)^2+\left(y-2\right)^2=5$  

•  $\left(x-1\right)^2+\left(y-2\right)^2=25$  

•  $\left(x-1\right)+\left(y-2\right)=5$  

•  $\left(x-1\right)+\left(y-2\right)=25$
