Point slope form of P(8,-6);y=1/2x+1

We just started the introduction into circles and i have no idea how to do this.

Complete the solution of the equation. find the value of y when x equals to 28 x+3y=28

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
