The value ‘a’ in the equation is the distance from the center to a vertex of an ellipse. (The point furthest from the center). What is a The center is (-1, -2)

The horizontal ellipse equation: (x-h)^2/a^2 + (y-h)^2/b^2=1

Please help me !!! And do not put a link or ill report you, type the answer.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
