Parallel/Perpendicular/Neither
When flipping an equation, you find to see if it is ________?
Perpendicular
Write an equation in Slope intercept form for the point (1,4) being parallel to 2x + 12.
y= 2x + 2
What is the equation for Perpendicular Lines?
y - y1 = m(x - x1)
x^2 + y^2 + 6x + 10y= 47
Center: (-3,-5)
Radius: 9
(x + 3)^2 + (y - 5)^2= 25
Center: (-3, 5)
Radius: 5
y= 2x + 3
y= 2x - 5
