The whole ellipse shifts down by 6 units.
If a = b then it is a circle; otherwise it is an ellipse.
Since it is not a function, you need to solve of y and you will have TWO equations. A plus and a minus one. FOR EXAMPLE the ellipse x^2/4+y+2/16=1 you could solve it as y^2/16=1-x^2/4 then multiply by 16 y^2=16(1-x^2/4) Now you have y=+ Square root of (16(1-x^2/4)) AND y=-Square root( 16(1-x^2/4)) IF you enter both of those and graph them on the same graph you will have an ellipse.
You move the graph upwards by 2 units.
You can do the equation Y 2x plus 3 on a graph. On this graph the Y would equal 5 and X would equal to 0.
y = -0.5x plus or minus any number
It is the Cartesian equation of an ellipse.
On my graphing calculator, a TI84 Plus, I can enter the equation into the Y= (a button) and then graph it by hitting the Graph button.
It is a straight line with gradient -A/B and intercept C/B.
There is no graph because there is no equation - only an expression.
y=x+1 there for answer is 2
The picture of the graph is in the related links section.
Same way you graph y = -4x - 0.5
