Question 595376
1) parallel lines have the same ratio of the x and y coefficients (slope), so you can use the same equation
___EXCEPT, the constant term is different because the y-intercept is different
___ plug in the new point to find the new constant term ___ (3) + 4(-6) = ? ___ -21 = ?
___ the new equation is ___ y + 4x = -21


2) a general circle equation is ___ (x - h)^2 + (y - k)^2 = r^2 ___ the center is (h,k) and the radius is r
___ in this case, the distance formula (from the center to the point on the circumference) will give r^2
___ (x - 4)^2 + (y + 1)^2 = 32 (not sure about "standard" form)


3) perpendicular lines have negative-reciprocal slopes, so swap the x and y coefficients and change one of the signs
___ like the 1st question, plug in the new point to find the new constant term
___ 6(-2) = -2(5) + ? ___ -2 = ?
___ the new equation is 6y = -2x - 2
