Points in the circle

You just need to use the equation. First, find the equation for the circle. Like this, x^2 + (y - 3)^2 = 9. Then, input the x and y values into the equation. If it's bigger than 9, the point is outside of the circle, if it's equal to 9, the point is on the circle, and if it's smaller than 9, the point is inside of the circle. WebThis formula tells us the shortest distance between a point (๐‘ฅโ‚, ๐‘ฆโ‚) and a line ๐‘Ž๐‘ฅ + ๐‘๐‘ฆ + ๐‘ = 0. Since the radius is perpendicular to the tangent, the shortest distance between the center and the tangent will be the radius of the circle. ๐‘ฅ = 5 This can be rewritten as: ๐‘ฅ - 5 = 0 Fitting this into the form: ๐‘Ž๐‘ฅ + ๐‘๐‘ฆ + ๐‘ = 0 We see that: ๐‘Ž = 1 ๐‘ = 0
