Abc has the vertices a(1, 4), b(3, 4), and c(1, 1). find the coordinates of each point of concurrency. 13. circumcenter of ∆abc 14. orthocenter of ∆abc

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
