circle intersection, find points
Find the points of intersetion of the circle x^2+(y-1)^2=25 and y=-7x+26 by solving a system of equations.
So far I got x^2 +(-7x+26-1)^2=25
now what do I do am I doing it right?
B) Find the length of the chord determined by the poibnts of intersection in question a. Express your answer in simpliest radical form.
C) Determine the distance of the chord from the centre of the circle
Like i said before this math is REALLY confusing to me, so details and step by step instructions would be amazing help.
