Answer is to be in the form Ax + By + C = 0 the pines passes through (3,-5) and through the center of the circle (x+1)^2 + (y-3)^2 = 25/4

If not, look up the standard form of the equation of a circle. Can you find the line that passes through the two points? Can you at least find the slope?
the center of the circle is (-1, 3) and the slope is -2 I think so the equation would be y = -2x+1 is that right?

so 2x+y-1=0
