The general rule for a reflection over the x-axis: $ (A,B) \rightarrow (A, -B) $ Diagram 3. Applet 1 You can drag the point anywhere you want Reflection over the y-axis ... WebSince the slope intercept general equation is y = mx + b, if you substitute 0 in for m, then 0x = 0 which disappears, so y = b. Zero slope gives a horizontal line that crosses the x axis at a given y value. Then, if we tried to substitute an "undefined" value for m, we really could not, but lets just imagine that we try.

Web10 years ago. The points of the intecepts are (2,0) and (0,5). to find the equation of the line, you need to put it into slope-intercept form which is y=mx+b, where m is the slope and b is the y intercept. to find the slope you do 5-0 where you subtract the second y (5) from the first y (0). you put that over 0-2, where you subtract the first x ... WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps! ( 9 votes) Flag WebJan 24, 2014 · 1 The general equation for a plane which contains the x -axis is y + c z = 0 for some constant c.
