Question

A circle representing a pool is graphed with a center at the original. Grant eneters the pool at point A and swims over friend who is located at point B

Answer 1

Since we have two point of the line, we can easily apply the slope-point formula for a line:

the two points are A=(8,0) and B=(-4,6)

then the slope will be:

`m=(6-0)/(-4-8)=(6)/(-12)=-(1)/(2)`

then the equation of the line will be:

`(y-0)=-(1)/(2)(x-8)\Rightarrow y=-(1)/(2)x+4`

the correct answer is the second option:

`y=4-(x)/(2)`
