Q:
# Find the points where the line y = x - 1 intersects the circle x2 + y2 = 13

Accepted Solution

A:

Answer:(-2,-3) and (3,2)Step-by-step explanation:sub in x-1 into yx^2 + (x-1)^2 = 13x^2 + (x-1)(x-1)=13x^2 + x^2 -2x +1 = 132x^2 -2x-12=0solve for x by factoring (quadratic formula, product sum etc..)x= -2 and 3plug in those values into y=x-1 and solve for y
