Question:
A is the point (−1, 5). Let (x, y) be any point on the line y = 3x.
a. Write an equation in terms of x for the distance between (x, y) and A(−1, 5).
b. Find the coordinates of the two points, B and C, on the line y = 3x which are a distance of √74 from (−1, 5).
c. Find the equation of the line l1 that is perpendicular to y = 3x and goes through the point (−1, 5).
d. Find the coordinates of the point of intersection between l1 and y = 3x.
e. Find the area of triangle ABC.

I have been a tutor for 2 years and have experience working with students of all ages and abilities. I am comfortable working with students one-on-one or in small groups, and am able to adapt my teaching style to meet the needs of each individual. I am patient and supportive, and my goal is to help my students succeed.
I have a strong background in math and science, and have tutored students in these subjects at all levels, from elementary school to college. I have also helped students prepare for standardized tests such as the SAT and ACT. In addition to academic tutoring, I have also worked as a swim coach and a camp counselor, and have experience working with children with special needs.
