The line with equation y=7 is graphed on the same xyplane as the circle with center (4, 5) and radius 3. What are the xcoordinates of the points of intersection of the line and the circle?
The slope of line l is equal to negative 5 minus (negative 2) over (0 minus 6) = negative 3 over negative 6 = 1 over 2. Since negative 5 is the yintercept, the equation of l is y = ((1 over 2) times x) minus 5. Sorry, but this feature does not work in your country because it is blocked by your country's firewall.
