1) domain: x cannot be -1/3, 0
2) domain: m cannot be 4/3, -7/2
3) domain: m cannot be 3
m =( Y2 - Y1)/ (X2-X1)
m =( 3-(-5))/ (-6-3)
m = - 8/9
I am assuming you meant a slope of 9/8 in your original question, so the points perpendicular to I are answer D.
Perpendicular means the slope is opposite reciprocal of your first slope given.
When the radius is 8, the area would be 201.06
Area of circle = pi x radius² (pi x 8²)
Answer: 63.63
